i've been fencing foil for the past 10 months, and epee for about the past month, both with visconti grips. I've taped all of my grips up quite a bit, but still have a problem of the weapon falling out of my hand or not being totally under control during intense fencing. I was at a competition recently and saw a Zivkovic grip, and figured that when I went to NACs in overland park i would try to look at some. Do you think the problem I'm having with my grips is because of the grip kind, or the grip size? and has anyone had any experience with Zivkovic grips, either positive or negitive? I'm looking at the B, Z, G, and GII versions of Zivkovic grips.
