I use towel grip mostly, only generic, cheap ones, and they last 3-4 week at best. Perweek, i usually play around 12-15 hrs, but it's divided beetween 2 rackets atleast, so it's about 18-28 hrs lifetime for those cheapo towel grips i used -well, since they're only around 0.15 US$ per piece, i must say it wouldn't hurt my pocket too much changing them more often.
supergrap didnt last me very long. last time i used it, the part of the grip where my index finger and thumb are usually gets destroyed after 2 hours of playing. =O
i use Gosen PU super grip... it feels really nice, but only last for 2 months. since i have sweaty hand, some black dots grow on it, and the adhesive didn't hold well after 2 months
i like to use Gosen Pu super grip too ....but i feel karakal better because karakal have more cusion >.<
The original grip that came on my Prince racket was useless, and had to be replaced after a couple of weeks (playing 15-20 hrs/week at that time). Apart from that, I don't think I've ever actually bothered changing grips - my Aerogear 800HT from c.2002, still has the original grip (didn't get another racket for 4 years, and I still use it sometimes) Maybe it's something to do with how you hold the racket? I kind of pivot it on my thumb mostly, and that's the only part that's really worn.
Wilson Pro soft black about 3-5 weeks i use my racket with wilson pro soft for 2h every day except friday and sunday
Well, too bad there's no choice for 1-3 days. That's how long it usually lasts for me because I have hyperhydrosis (which is a skin disorder which causes me to sweat a lot on my palms)
The Tournagrip tennis grip is meant to be better when wet (good for people who sweat a lot). Maybe you could try that on your badminton racket? I think it'd last longer than whatever you're using now. 1,100th post
i also got a yonex black supergrap overgrip, got it 3 months ago and still using the first one and no, it is not even STARTING to look like garbage
my overgrips are starting to last ever since i have a wrist band to reduce the perspiration. The only thing that does it not last is the stock grip that is beneath the overgrip everytime i replaces it.
