I have a Sterling B/J. The performance was dismal until I purchased some White Diamond tips and had the put on.
I also have a Stealth AT-1, that one is just a Jump cue. It came with a special Buffalo hide tip that works great, also has a nice thick, stiff shaft at 14mm.
With Jump cues, so much depends on the stiffness of shaft, and the type of ferulle & tip.
