I purchased the OB-2 shafts to use on my playing cue. I have always favored a smaller tip dia. and reviews I had read seemed to indicate that this was a superior product. I am well pleased with the hit these shafts deliver on my Schon. I just wonder if anyone had some probs. adjusting to the lack of a nice white ferrule when sighting with these shafts....It took me a couple of months to really lose the subconsious thought that something was wrong.......guess 40+ yrs of playing with nothing but white ferrules was more of an issue than I considered it would be. Also....what kind of maintenance issues ....if any.....have these composite wooden ferrules developed?
