The players I GM like to see what they can get away with when it comes to Tech combos and they come up with some good reasons and a lot of the time I have to tell them "No! It ruins game balance."
But I still liked how they sounded. so here are some of them
Run two different smartlink feeds to different eyes and use an attention coprocessor so you can use akimbo smartlink
Set up a Pilot inside of your smartlinked gun and give it a gunnery program to assist like a spotter in order to feed extra data to the smartlink by makeing complementary firearm skill checks
They also tried a comlink inside the gun running a decent command , edit, Tac Net Programs(I still gave them the Tac net bonus) they then put the Team hacker in the guns node he had the Gun Trivia and Ballistics Physics skills as well as math SPU, and they wanted the hacker to be able to enhance the processing power of the smartlink
