I've been reading for a while and just recently signed up. Thanks for all the info so far. After reading tons of threads, I picked up some DG AW, DG 105 and 901. Haven't used the 105 yet. I know AW isn't a QD, but I read that some people use it as such. I'm considering purchasing FK425, HGAS or DG FC&S. Any feedback who have some or all of these would really be appreciated. And after using them, did you lean more towards one over the other? Thanks!
