I had to hit with a Speed 300 when I was out of town once and it was the only frame this club had available for a demo. I hated it. It felt off and pretty stiff, and actually pretty sluggish through the air because of the balance. I actually think the 315 version moves through the air more easily, and is a far better stick. The 16/19 version of the 315 Speed is a stick not many people seem to like, but every time I try it, it's excellent and gets the job done. Just swings so cleanly, but it's a string sensitive frame.
Carry the flag, friends.
