Don't know about jumping, but I can get lots of draw and spin with my break cue, not that I try anything other than a center ball hit for breaking with it. Since I don't jump balls, I don't have a clue.
Actually, the BEST solution is to take the shaft to your local cue repair guy. As it is spinning on the lathe, have him take the corner of a utility blade and cut several grooves in the tip surface. I generally start at the center and work my way out...leaving 4 or 5 circle grooves. The grooves allow the tip to REALLY hold chalk well. Easy solution.
