I have an OB 2+ pro taper also. I bought mine last year at the CSI Nationals in Vegas from Royce (great Guy!) I was shocked to hear of his passing!
I spent an hour and a half hitting balls around on the practice table with all the different shafts they had. In the end it came down to the 2+ or the Pro+. Since both felt very similar to me I went with the 2+ because, for me, it felt a little better than the Pro+.
Royce was very patient with me while I decided which one I liked best. I even spent an hour at the Predator booth hitting their different shafts until I decided the OB felt better to me.
I agree the feedback of OB is a little lacking. The only cue I have shot with that had the best feedback, IHMO, was a Sugartree. But I do love my OB cue.
Sorry I can't give you the feedback on the Pro+ you are looking for.
