My jumper has tht phenolic tip on it and I can put the shaft from my playing cue on it. No contest, the phenolic opens up a world of jumping possibilities that are not available w/ my regular tip (Tiger med or hard, dep on shaft). I had trouble with control at first, but thru practice, gotten used to it.
Edit: I don't have the SLedgehammer type tho. also, I didn't vote coz neither option seemed right!
