Good question. I think a little different than some people. First off, I think shafts are like automobiles. There's one made special just for your style of driving/playing. You just have to find it.
I will probably sell some of the Bender shafts one day. I can't and don't play with all of them. Most of them have been sitting in cue cases and now they get a chance to sit in a display case.
I like testing out different shafts to see how each of them perform. I've been on a quest for a lot of years. Sure, if you can play decent, you can play decent with just about any shaft. It's not the arrow, it's the Indian, they say. But I think they're not entirely correct. Each shaft has different properties and with the different tapers, come different playing characteristics. Some of them more important to some than to others.
I'm more concerned with performance than I am looks and just as long as I think there is a better piece of equipment out there, I will keep trying them. Unlike some people I don't think the regular trying of different equipment hurts a person's ability to play at their highest level. Of course it's critical for one to become completely syncronized with their playing cue and shaft of choice but for me, it doesn't seem to hurt my level of play to experiment here and there. I'm still a banger.
