Can anyone tell me if the Z3 taper is identical to the OB Pro? I think they are both euro/conical tapers, but want to know if they taper at the same gradient / feel like the same thickness. Reason I ask, I have played with an OB Pro on a Schon LTD for many years and really liked it. I recently moved to a Revo 12.4 on a Predator Throne 2-2 and am having problems getting on with it. Aesthetically, the Predator is beautiful ... just having a problem getting the feel of the Revo. I want to try a Z3. Thanks.
