i have one of those... but it's still sealed in it's wraper..the strong grip one... haven't got to use it yet... it seems like over grips still figureing it out LOL ..haha
I didn't try those two, but I have tried similar models before. They are the replacement MP grips and leather grips and they are thick, comfortable, and very sofy. Genuine Yonex grips are very nice but expensive, Very Very expensive.
They are queit comfortable actually. In term of durability , i will still yet to find out. Actually they are not that expensive cost around Us$3 each.
I have tried AC133. I got it from my Japanese friend. It's comfortable, not too tacky and durable(3-4 months). The thing I like most is it doesn't have the adhesive on the wrapping surface which keep my racket neat and tidy.
I am using the Excel grip, but mine is those 3 in a pack, just like Super Grap, 3 in 1. Nice grip, very soft. Bought it at Yonex shop in Far East plaza, Singapore, about SG$20, I think, can't remember clearly.
When i went to WTC , they dont have any of these grips available. They don't even sell Yonex towel grip. Frankly speaking i'm getting sick of going to WTC Yonex store. The staffs there is not friendly, i can say that they dont seem to be happy working there. Oh well at least i can do something about it.
