Stinger
I just got one from username "BVAL" on this forum a week ago. The construction looks great. (I was going to buy a thumper, but found the used but very good condition stinger instead.)
I am in Houston on the west side of town (shoot at Slick Willies at 20900 Katy Frwy @ West Green) - if you want to try it.
As a breaking cue, it should be excellent.
I find the phenolic tip to be quite hard, and difficult to impart much english to the cue ball. It hits fine with very close to center english. I tried to shoot some racks with it.
I have not jumped with it much, but like the regular cue shape end to it - rather than a flared out jump cue butt like some out there.
