Ok, Q&A
Street Cred/Rep - There's no mechanical street cred or rep; but some people might know you, and you might know some people.
Arsenal Combat Rules - I can't remember all of them, but assume yes, and I'll have another look at them tonight. If there are any of them people specifically want to know are in, just ask.
Critias' Errata for Way of the Adept - It is in play.
Travel - Your standard arrangements are up to you, but I would say - don't think you'll need to, or expect to, take all your gear with you all the time. For me, part of being a top Shadowrunner/taking this sort of 'Crash Crew' work, is that sometimes you will be dropped somewhere with just your pants, commlink and a pistol; or that there will only be one way in; or will even be on another continent.
Just so you know. A Citymaster moving base of operations does sound cool mind... and I'm sure there are plenty of secret passages, or bent border guards... a Citymaster *is* pretty conspicuous though. I guess you could mod that to make it less so, but while you can fool some of the people some of the time, you won't fool all of them all of the time....
Xethereal - Haven't forgotten your PM, will be on it.
