The senior version of the M1 still has a lot of the feature and minimus carbon of the pro and pro+ The big difference is weight - if that’s the most important thing to you, spring a bit extra for the Pro or Pro+. Otherwise this stick (I ordered with the more extreme blade curve) is really good at throwing shots down the ice and has led me to have a better shot. It’s light but not too ridiculous, somewhere in a nice medium range so poke checks are easy but there is weight when you need to shop a 5 hole across the ice. The slide grip is great, not so much sticky stuff so you can poke very quickly. Over all, I am really happy I bought this stick.
My Daughter loves the Warrior stick as her first ever goalie stick! They guys at Willies couldn't have been more helpful to me as a new parent learning what a goalie needs!
