This time last year I picked up a gravity point5 17.5 size. Since then I've put over 2000 trouble free miles on it. The only thing I really don't like is the size, I can ride it but I'm always feeling it could be a bit smaller and it's a handful in the tight stuff. I don't have the money for another complete bike as I'm saving for a road bike so I'm thinking I'll just get a smaller frame from Bike Island. They have the same frames with a couple different fork options and sizes. Probably go with the Tora fork combo and put it on my wife's bike as I already have a perfectly fine Reba.

Will the smaller size (15.5) make much of a difference in the handling? I realize it's a semi slack head angle, and am hoping a smaller frame will shorten things up a bit and give me a little better connection to the front wheel.
