The M+ features two stainless steel rings, one fitted in the cup and one fitted outside. The two rings give them the ability to really place the weight where it’s needed in order to maximize performance in their new design.
Mowl kept all the specs about the same with the M+ and reduced the weight by about a half gram. The same specs paired with 2 sets of weight rings gives the Mowl M+ a much improved weight distribution for incredible spin power and maneuverability on the string. It plays fast and bouncy with amazing stability and control!
