i was looking at cues on ebay and this guy had a bunjee exotic jump cue for sale.....and it came with a 5 or 6" extension thats just screwed in (between the butt and the shaft i think). My question is what would be the advantage to something like this? I think most jump cues are around 40 to 41 inches......my sledgehammer jump section is right at 41......so would the extra 5 inches help you reach jumps more in the middle of the table? or is it better for shorter players or taller? Im wondering if you can buy these extensions somewhere to fit other jump cues.
