I recently got a purpleheart shaft with a Schmelke I had on order. It has their standard pro taper, and a 12.5 mm medium hard tip. I had originally thought I would use it for breaking, but it plays rather well. I had expected it would be too stiff, but it turns out that's not the case.
I'm not crazy about the current tip, so i'm going to switch to a Kamui black soft, and see how I like that.
