Hard to say without seeing you in person, but IMO there is no wrong, just different. 3/4 is a lot of reverse, but if you are able to set your thumb and hold the ball without death gripping, then go for it. If your swing is loose enough, you can repeat shots, and YOU like it, then go with it. I wouldn't make a decision until you have bowled with it for a month or two, checking to see what kind of blisters or bumps you get if any.
