I could be wrong, but when you use to go to OB's website and get a description of any cue it would tell you its made from the SR-6 design/format. You read it now it leaves out SR-6 and just says its stiffer and stronger. Are they still using it? I think the description for how they balance the cue is now worded different too. Not sure if it means anything but possible they changed how to balance the weight of the cue as well?
