I switched from tightly wrapped to lightly wrapped once a coach told me to do so. Now I accustomed to it and cannot change it back. He said having a more comfy feeling is the purpose of the overgrip. How about you guys?
I used to grip tightly as well but have found that if you play frequently enough, you'll eventually get blisters. I now grip moderately. It also depends on the grip type, some ahave more cushion than others.
Is getting cuticle on thumb the result of playing too frequently on tightly-wrapped grip, or due to improper handling??
Neither, that's a sign of dryness. You need to use more moisturizer/lotion on the cuticle to soften it. Cuticle is important because it's a barrier for keeping bacteria out.
