Migrating from the IG Speed MP and pleasantly surprised at the playability of the Speed Pro. While only minutely heavier (3-grams) it generates significantly more inertia with a swing weight of 328gm as opposed to the Speed MPs swing weight of 315gm. To my game this equals less effort needed to get the same pace of shot. I am fairly strong, so the stick doesn't feel unweildy, but I wouldn't recommend for U12 players as the added swing weight may cause them to "cheat" on the technique, and perhaps cause joint and/or ligament issued if they have poor technique to begin with. Just my 2c.
