I'm trying to decide on a 130mmish trailbike frame.  I currently ride an old Jamis with a single pivot and no lockout that will bob and bounce if I don't pedal smoothly, so one of my desires on my next bike is for it to pedal well.  Currently I'm thinking FM 1001, LCFS958, or maybe a P1. The numbers keep pulling me back to the 958 but the single pivot pushes me away.   Are there advantages to the single pivot besides simplicity, and am I wrong in thinking that a horst link or similar will pedal better while remaining plusher on the way back down, or am I asking too much and should rely on lockout to take care of my issue?
