Well, again, I have my table in mind when I make these recommendations (as I don't know about yours), and we see combat every session, so I should have qualified that REA vs INT statement accordingly. I'm also an REA/passive dodge whore - I always try to get it as high as is reasonable. Perception is oft cited as the most used skill in D&D, and probably holds true for SR, so YMMV, but between a good INT anyway, your skill, and your ware, you should be set with Perception.
Anyway, while I may seem to have good ideas they may really only be good ideas for me

so, y'know, ignore me if something else makes more sense to you.
That being said, the thing with the shock glove is it uses half of your opponents Impact armor, with a 5S dam... Your ceramic knife gives you what? a 3P vs Ballistic armor which is usually higher than Impact anyway?
