I hit with it for a minute. 12.2 diameter shaft with the medium tip. Played some hard center ball shots, some draw shots, and some max sidespin stop shots.
The taper is very good. I'm not a fan of the conical taper on the Revo. The hit felt nice; to me it was a nice happy medium and felt very lively.
His ad says "unlike hollow or overly thin designs....". That means to me it will squirt much more than a Revo, or even a 314.
I play with a Revo 12.4 and my first guess at the deflection for max sidespin stop shot was correct. We'll have to wait for someone to test it. I think it will be close to the Revo.. maybe slightly more.
