Your Legs at Availability 14 are Illegal without 2 Restricted Gear Quality which in itself is illegal. I'm working on a Prime Runner Sum to Ten build right now, mainly to avoid the Availability issue that makes yours invalid. Though I'm going the other way with them to shove go much stuff in them it's falling out, you'd be surprised at how fast 86 Capacity fills up. I'll post it once it's finished, I finally got the 'ware figured out or at least figured out that cramming more in is no longer feasible cause those limbs get super expensive super fast.
You are right, it is illegal! Did not realise the optimization added +2 availability, and my chummer didnt track the availability properly. Anyway I edited the build above. I added the quality biocompatibility and reduce the grades for both legs to standard from alpha to make it legal again. Also drop the grades for the cyberarms to used from standard. Using the freed up cash to get synaptic acceleration instead of boosted reflex and 2 additional armor for the cyberarms. Dropping them to used grade allow me to pick up the 3rd armor rating. Net change is -5 karma, but gain 1 initiative and 1 defense pool, +2 armor and increase my remaining essence to 0.34 from 0.16. Come to think of it. This is in fact more efficient than the first build. hahahah
Getting closer to my build now... Drop the Legs to used to get Didigrade and you're set. Prime Runner let's you add Bulk Modification for even more gooey goodness. I think the Steamers full of NeuroStun & an Internal Air Tank will be the funniest thing in a while. But Redliner is still trash... imagine Narco & Pharmaceutical Grade Kamikaze! Way better than Redliner... + 6 Boxs for Physical (need some where to offload that Stun Damage), +2 Body, +1 Strength, +2 Willpower, +2d6 Initiative, +2 Physical Limit, & High Pain Tolerance 3. All for the low low cost of an Addiction Threshold 2 or 1 roll every other week against 10 dice if not Addicted or 14 if Addicted (no real reason not to start at Mild for the Karma.) Cyber Singularity is worth it in my opinion & greatly shores up traditionally the Street Sams most well known weakness. Willpower 5(7) or (9) on Kamikaze. Shake off Stunbolts like rain once the Mages counterspelling dice get added on. Still trying to make that Pain Editor fit though (it's a pain that I haven't been able to overcome that last hurdle stopping it from perfection.) I might have to bite the bullet and drop my Rating 4 Hydraulic Jacks, I just really wanna be able to jump off 4 story roofs for fun.
Critiques on what you have so far. Datajack=Waste... get a commlink, you'll get DNI & not waste Essence for it. Internal Router=Waste... you don't have much that gives Wireless bonuses & what you do have you already have a Neural Connection to so activating it is a free action. (A) Reaction Enhancers 2=Waste... (U) Reaction Enhancers 3 is better in every way & about the same cost. Cybereyes=Giant Waste! Get a SmartLink in your eyes... you A. Waste Essence & Nuyen B. Leave your eyes open to bricking to blind you (kinda makes the Internal Router a complete and total Waste) C. Vision Enhancement 3 in Contacts (they have to be Wireless anyways) the rest goes into Glasses for everyday wear & a Ballistic Mask for Runs.
Oh... because it's such a heinous assault upon everyone who has the misfortune that happens to see you, Never Stack Sleeping Tiger with a Synergist Line Coat!!!!! Wearing a Sleeping Tiger is bad enough in Public especially since you aren't an Ork or Troll, but committing a fashion faux paus of that caliber should generate a crowd of villagers with pitchforks & torches to chase you out of town like Frankenstein Monster!!!!! Also... Ballistic Masks are cooler, conceal your identity, & don't ruin the -2 Penalty to Perception Checks from Ruthenium Coating.
i dont mean to play the char. its just a showcase that cyberlimbs and redliner is no longer as weak as quite a few people see them. As for my augmentation choices:-
1) i think redliner is a steal. but its just my opinion and because i prefer certainty in my char. If you prefer drugs as long term measure, you can surely definitely go that way.
2) datajack is just cool and gives you DNI for a cheap cost. Plus you get a free noise reduction. Throw in a cyberear with 3 antennaes with the S-n-M combo with a Evo Himitsu and you can get 15 DP to avoid matrix perception. A commlink doesnt give DNI. You'll need a trode for that DNI (in a fight, someone can pull your trodes off, or at least at my table you can)
3) Internal router is perhaps the most important thing for me as a Sam. It gives you access to wireless bonus for your cyber holster and skimmers, and most of the smartlink function (except the +2DP), without actually ever needing to turn on wireless. Save you lots of grief from bricking. When you add in a vision enhancement for your cybereyes, the internal router will help you get the +2DP for your perception test.. Realistically speaking, you can slave your devices to your decker. But if the decker is actually using a deck, it will at most be device rating 3 and will only able to take 9 devices as slaves. I dont think he/she will appreciate you asking him/her to protect 5 or 6 of your devices. For me shadowrun may be about teamwork, but it is also trying to be as self sufficient as possible.
4) Reaction enhancer 3. If you have the essence, why not. Just that when i was playing around with the build, it takes too much essence because you have to buy used grade for a R3. With biocompatibility, a R2 alpha is 0.42 essence. R3 used is 0.99 essence. A difference of 0.57 essence.
5) You can go visual equipment route. Personally i prefer cybereyes so that you dont have to wear contacts (wireless must always be on), glasses (can fall off), googles (conspicuous). With internal router, all wireless bonus is accessible except the +2DP from smartlink.
6) For the sleeping tiger and synergist line coat combo, other than being really munchkin, i dont see why its a fashion faux pax? Given that both are custom fit equipment (which by definition is a perfect fit which doesnt even allow for minute changes), it should fit your char perfectly without looking out of place. That said, i really have no idea what a sleeping tiger should look like given the lack of description. I havent seen any description that only orks and trolls wears it.
in any case, the build is just an example. It is by no means optimized. Please feel free to use or change whatever you like. I am sure you can make a more optimized char than the example above
