I have the Head Hydrosorb Tour synthetic grip on both of my sticks (Head Youtek Speed MP 16x19), but one is a #4 and one is a #3 grip size. Both have (my favorite) Yonex Super Graps over the Hydrosorb Tour. I like the feel of the #3 better and would like to reduce the #4 without shaving. What would you recommend? I've read of the Laserfibre Reducer Grip, and that may be best. But then I'm also curious about TennisWarehouse's 1.3mm leather replacement grip because I'd like to maintain (or increase) the mass of my racquet, and could count on leather to do that. Can I stretch the leather grip to the point that it is thinner than the Hydrosorb Tour that I have on there now? Or, should I go the bare handle wrapped in athletic tape with an overgrip? I've tried playing without my overgrips, but can't do it. Thanks for your input.
