erm, i use Hi-Qua... this one: just make sure you put your fave overgrip over it, i dont think it absorbs sweat very well. http://www.mybadmintonstore.com/shop/product_info.php?cPath=25_29_51&products_id=88
The whole point is NOT to use overgrips seeing as I don't have a job and my parents don't give me enough allowance to keep buying them They're pretty expensive in Canada. A pack of a Super Grap (3) is almost $10 tax included.
he might not have a credit card yet since he's still getting allowance from his parents... but then again, i dont know. but overgrips are same as replacement grips, they probably last the same time if you play with either of them (sweat) overgrips are cheaper than replacement grips too.
Try Super Full Grip of Tecnifibre http://www.tecnifibre.com/index1.html?en Search under Accessories of Tennis Products. It is quite thin (1.8mm). And most of all, if you wrap it very very tightly and with minimal overlapping, it will be thin enough and one piece can serve as two pieces
i use Wilson Soft sponge overgrip i think it's 0.44mm or something along that line... i even measured the pack it came under 1 cm and theres like 14 layers so u do the math ...
One question, 1.8mm isn't a thin grip for badminton, so how's that a thin grip?That thickness is triple the thickness of my yonex super grap which is only 0.6mm.
