Yea +3 (so 4 total) across the entire grip is pretty typical to achieve "midsize", and an additional 4 wraps as well on the bottom section (so 8 total) to get midsize and the +4 on the lower hand feeling.
So wrap it 3 times the entire length of the grip and then wrap the lower half another 4 times? Doesn't sound too difficult. Is there any specific wrap I should purchase?
