Aris worked with me to customize this grip for the new Mybo Wave XL, with a higher 50 degree wrist angle. The first grip didn't fit properly due to slight changes in riser design compared to the older Wave riser. I sent pictures to Aris and he sent me a revised grip free of charge, and it fit perfectly!
Grip positioning is very repeatable because of the slight palm curve in the middle, which creates a subtle pressure point.
Terrific grip and excellent customer service!
