Slugo, did the 725 you shot have an adjustable comb? The only one I saw on Browning's site has one. When I got the XS Skeet, I waited a while for the 725's introduction but went with the XS when it didn't appear that Browning was coming out with a 725 with a parallel stock. I say go for it if you want it.
As for it being more "nimble", comparing it with an XS Special with adjustable comb the 725 is almost a pound lighter. Some want the extra weight, some do not. I am guessing the weight differential has something to do with why it handles for you like a 20.
As for the grouch picking on you,
he wouldn't do it if he didn't like you.
