Sorry I cant help you out in person, we are pretty far apart. But I can give you my opinion on the three main FX bullpups. I have owned Impacts, a Wildcat, and a Maverick. I can tell you they all feel different, at least to me. The Wildcat has the best ergos by a long shot, that stock is really something wonderful. The Impact and Maverick are pretty good too, but I cant stand the factory grip. If you have big hands or a lot of meat in the web of you hand you will probably want to change grips. I have been really happy with something like the Strike Industries 15*. The Impact in particular I found uncomfortable where the top of the grip area meets that big plenum, it was digging into my hand. Same with the Maverick, that hard angle at the top of the grip where it meets the chassis isnt great for me.
What ever you choose I suggest looking at Bullet Central, they have versions of all three on a huge sale right now.
