I' m using the Challenger and haven' t had a single problem with it in the last year I' ve owned it. No negatives here. I wasn' t sure whether to get the 6" bar with the 4" frame or the 9" bar with the 5.5" frame so I got the bigger one just to be safe. I could definitly get by with the smaller one now that I' m shooting a fast bow. The weight difference isn' t much either; 9.87 oz for the 4x6 and 11.43 for the 5.5x9.

Before I got this I borrowed an older check-it and I see where they get thier name. After every shot or two I had to check it to see if it was still tight. This sure-loc is always right where I left it. It is a great sight bar.
