I have a 725 with 32" barrels. I also have a 30" 625, and a 32" 625. Both 625s have adjustable combs which I like. I just sent my 725 for an adjustable comb today, as it fits a tad low.
I like all 3. The 725 is a tad lighter, although I really don't notice when I'm shooting. I don't really feel recoil as I'm 6 ft and 350 lbs.
I find the lengthened forcing cones really smooth the guns out. They tend to whoosh instead of bang.
I just bought the 725 because it was new. I'm quite happy with the 625s as well. I use the 32 for sporting, and the 30 for skeet, although I don't really notice a whole lot of difference.
I shoot low gun all the time, so the 30 is probably a bit better for skeet.
