backinit I do from time to time. Still have plenty of them from 3 years ago (3 pc.). Have also tried the newer version and can say they are the same for me. Always long, as far as any. Spin.....it is whatever you can do with a ball. I don't look for that myself, but they will check up fairly easy from close in, for me.
The new logo....🤮.
backinit They did make a urethane version
And it was total crap. They shitcanned it very quickly and never tried again.
The new ones are also a 3 pc., but no urethane.
They also had the Gamer Tour and I found it not as good as the reg. Gamer. Not around any longer either.
iirc, compression is around 75-78.
