[Closed] Need help - suggestions - bike build

Ok, ive been riding a Trek 6500 15.5" and my current ride is a Fuel ex7 again 15.5".

Having felt a little cramped on the longer rides, i picked up an Orange P7 in 17", went for some big Dual Air Revs, built the bike up and its too big, doh! no ball clearance as it where!! I wanted a bigger travel rig for some jumps and stuff, but also bigger frame for those hills etc. So now the kit i have is too big do i:

Lower the Revs down, although im really struggling to get my hands on some travel adj spacers, is the 15mm going to be enough??

Buy a smaller frame, was looking at the On-One summer in 14", it has a longer top tube so should be better!

Buy some smaller forks and sell the revs??

Oh im a 29" leg and about 5ft 5 ish height!
