I can't say I love it but that isn't all the AM831's fault, I would have the same riding issues with a Hightower. It is the bike that I pick first even when I know it is going to be way more bike than I need, so I guess I like it a lot? Either that or I don't like my other bikes, haven't decided.
Geometry is good, suspension platform is good, ride is pretty good, it definitely gets looks on the trail, but all around just good.
If you're asking this question you should probably return it or try to sell it, there is a high probability it will never feel right even if you do find a way to shorten it up a little.
