Spektra edge x

[bigbadripple]

Fellow artist at my shop has a Edge x and hes digging it. He is using with an FK grip. I wanted to try it and use it with my cheyenne twist grip but when i twist it onto the edge, it wont let me twist because the entire grip twists. We were wondering if it was because of the o ring on the top of the threads that prevent the cheyenne from tightening. Anyone else have that issue? Thanks

*update* 4-3-15 Was informed that this issue is resolved in the new edges (the one im referring to is an older verison). I"ll be using the new info from the FK crew to resolve this. Simple fix. Kick ass customer service as always.
