In all honesty I've never taken it - I'll give it a whirl on my next game as an attachment to Huggy.
I don't power game (I'm not accusing you of this btw) as I want to play games which are fun for both me and my opponent. I particularly like Expert Cheater as it adds a new bluffing dimension to the game - whilst I appreciate it might not be the most potent upgrade he has, it is always my first pick.
Holy crapola - I've not been playing it where it effects my models. I have a few apologies to make...

+1 to this. Lynch has been a very rewarding master to play to date. Competitive and, most importantly, fun.
