“As a busy Pro coach in 6 Tennis Centre, 6 days per week – I’m proud that perforated Hi-Tac give me ultimate Grip even in humid “summer down under conditions in Australia, My clients love these sensational grips! I am trialing the black Smooth grips and I’m sure it will be great just like Hi-Tac. The OTZ Band Dampeners perform great. They provide much more dampening than my 4+ years of playing with normal plain color rubber bands. The OTZ band damps don’t dry out and crack under the hot Australian sun. I love the variety of colors and the very cool Z logo. Go for it!
