The OB pro is gonna be more like ur g core as far as hit and feel the ob2 is more of a soft hit u should go with one of the new ob plus shafts I hear nothing but good things
Just got the OB 2 plus about a week ago and using a Joss butt. My OB is 11.75 with a maple ferrule. It is a soft hit which I personally like. I am really starting to love this shaft. I can now move whitey around in really tight spaces with accuracy better than I have before. Just my 2 cents as they say.
The OB2 plus and OB Pro plus are 11.75 mm with a conical taper
Both shafts are considered ultra low deflection
One of the big differences in my opinion is wood ferrule vs. plastic ferrule
