I have the new Jacoby Ultra Pro shaft. It came with a Tiger Everest that was completely dried out. I put a Zan Hybrid Max on it. It weighs 4.07 ounces and measures 12.88mm at the top of the ferrule. It has an extremely long pro taper, and flexes a little but not enough to make it whippy. The shaft does not feel overly stiff, the hit is very solid and feels almost like a non-LD shaft and gives a little more feedback than my Predator 314-3. I like it a little more than my Jacoby Edge Hybrid which has an Onyx tip so its kind of hard to compare the two.
