I have a Santa Cruz Heckler w/ a DHX 5.0(air) w/ propedal, and even though it's a simple single pivot, it doesn't bob at all under power unless I'm standing an giving it hell(but I don't get out of the saddle unless I'm at the peak of the hill). Basically, I'd agree with Gastro, the shock/pedalling platform should determine how much bob you're going to get out of these suspension designs. Personally, I know the Fox 5.0 and RP23 shocks work well in controlling bob, even in single pivot suspensions!
