If it were me, i’d get the bullit. Those bikes are primo. Single pivot way over built. That thing can handle a lot of abuse. It could probably out live some of us on this forum. :0)
I’m a heavy guy, so i like bikes with less pivots. Less pivots equals less things to become loose and worn out in the long run. The only bad thing about a single pivot is brake squat/brake jack. But since you would be coming from a hardtail, you wouldn’t even notice. You can get used to it and change up your style a bit to compensate if it’s that bad. It’s usually not that bad unless you’re riding a downhill shuttle trail that has a lot of braking bumps.
