Way too slack with 160mm forks, rode absolutely horribly. If you run them at 140mm the axle to crown is still longer than 32 Float 140’s, I could tell the difference. Not only that you are carrying around an extra pound in weight for a slight stiffness increase, which IMO, unless riding really rocky stuff you don’t need.
I think you will struggle to find the need for anything more than what a 2012 RP23 can offer, it is seriously good shock.
If you think you need more bike you would be much better off with an Alpine.
