On an 07 apex if you remove the inside rivet will it only affect the low end RPM and not affect top end at all? (weights have 3 rivets, inside, middle and tip) I am hitting about 9500-9700 RPM initially out of the hole and about 10500-10600 on top end. Just looking for a little more RPM on the hole shot. Thanks, Mike
