I use the wire, just be sure to leave the twisted end long enough to bend it back into the grip, about 1/4" tp 3/8". I also put the twisted end toward the bottom of the grip and point the end away from my finger tips. This way if your hand gets pulled from the grip your less likely to snag your gloove or flesh on the tail of wire.
i never had a problem with any grip i have ever used. to get the grip on i spray some lube to get it on and when it dries it makes somewhat of a seal and they stay snug for ever, like i said never had a prob! :thumbsup:
the girp actually has a hard plastic / composite center that the clamps attach to and it never moves... ever.... set it and forget it.... the cool thing is with the center being like it is it makes the grip a bit biger in GIRTH!!!!!! :lol:
