Looking to pick up a Pros Pro Stringing Machine Challenger 2 for personal use, but I understand that machine is built to cater tennis/squash rackets. 1) Can I use the existing frame support on the machine for badminton rackets, or will I need to purchase badminton specific ones? Such as this Pro's Pro Stringing Machine Badminton Racquet U Frame Support They seem to cost about £11.95 and I'm guessing I would need 4 of those which would equal = £47.80 Or would these fit as a substitute? https://www.racquetdepot.co.uk/gamma-l-shaped-badminton-shoulder-adaptor-4-pack/ 2) I also assume the existing fixed clamps aren't suitable, anyone recommend any good fixed clamps? My friend uses Penta clamps and only 3/5 teeth grips onto the string, pretty bad Thank you for your support!
