So I purchased a Pro's Pro Challenger a few months ago and was unsure if the 3-Prong base clamps (attached to the machine) are usable for Badminton racquets. I saw 5-Prong clamps for purchase online which are for badminton use but I don't want to purchase them if I can use the 3-Prong clamps supplied with the machine. Currently I have been using two Flying clamps from my old machine and I purchased two Yonex Flying Clamps (they were inexpensive)! Anyways, if the 5-Prong clamps are better I would probably pick them up but I also want to know if and WHY they are better or badminton-specific. Thanks.
