Re: AE vs AW
If you fire factory match ammo, this doesn't make much difference, but it might if you like to handload. The AE mags lack the small composite insert at the front of the inside of the mag, which gives a couple extra millimeters to work with in seating depth and still have your ammo feed from the mag. For me, the biggest deciding difference was about $2000 to spend on ammo! (A wise man once said, "don't spend so much money on shootin' gear, spend it on improving the f&*kin' shooter").
I will also say that the two-stage on my AE, which is right at about 3.5lbs is great...smooth take up and clean break. I don't know if I'd want it lighter. I think it would tough to go "wrong", but with my AE (since I pretty much knew I was going to stick w/ 308), I can say that I haven't come up on one time yet that I wished I hadn't picked the AE...and I'm still working on using up the 1500 rounds of BH match I purchased with the extra $.
