I have had tried a Sledgehammer, (seemed a little butt heavy 'To Me'), I own a Fury, its OK, a little whippy though, and not nearly a product made by a 'Craftsman'. I purchased a Stinger almost two years ago, its a great cue, love the way it breaks, jumps like a bunny, and it is one good looking cue. People actually think its a SP, (I have the Cocobolo Model). I haven't tried an X-Breaker, but I am perfectly happy with The Stinger, (American Made by Jerry Powers, Clyde, Texas). This fact goes a long way in my book.
A side note:
I recently had an unfortunate 'accident' during a tournament...my case hit the floor with my cues standing in it!

My Schon LTD and my Stinger hit the floor! Unfortunately The Stinger took the brunt of the force and hit the bottom rung on a chair, (shattered the shaft in two places from the ferrule to about 4" up the shaft). I was Pi**ed to say the least. I pride myself on taking very good care of my equiptment. Called Jerry with my disturbing news, his reply, 'send it to me, if it's just the seal coat I'll repair it and fit it back to the cue, if the shaft is broken, I'll just send you a new one', my reply, ('a shaft'?), 'No, the time to make a shaft to fit your cue, to maintain weight/balance etc., would take awhile, I'll send you a new cue'. Thats right, a brand new cue! How 'bout that for customer service!? Don't see that much anymore...
Anyway, long & short, I sent the cue to him on Wednesday, the following Friday a BRAND NEW Stinger arrived at my door. Second Generation Tip, only been produced for two weeks now, Forearm Signed by Jerry, Stinger on the Shaft, along with 'Made In The USA'...sweet...
