I had new tips put on my cues a while back and the person who did the work recommended elkmasters. i'd always used the harder leather but supposedly they were too hard and the elkmasters would be much better at avoiding miscues. so the tips are ok and I don't miscue often, but I never did miscue much and I find I cannot jump at all. i'm an old guy, and back in my day, there wasn't much emphasis on differing equipment, so i'm pretty ignorant of the new technologies. I don't (won't) use a jump cue. its like using a dictionary to do crosswords. so if somebody would like to respond, I would like to know what is the best tip to be able to jump with my playing cues. billy p
