Hey guys, I have an X01 that Ive had now for a couple months. I dont claim to be a pro by any means but I am able to get a pretty decent and level edge (better than the local rink can provide anyway) and using a 90/75 FBV spinner. My question though. Like mentioned above, I am able to get decent edges but have noticed something with my wheel. After using the Fine Shine for the final pass it leaves a dark residue on the wheel (not the issue) but I have noticed this dark line does not go around the entire wheel, almost like the wheel is out of round. To the best of my recollection this has occured from day one and this is my first wheel, so Im not sure if its the wheel or something else. I have tried several times to do a pretty significant dressing thinking it would resolve this but it never does. Like I said, this is my first wheel and I have another ready to go but haven't used it yet. Is anyone else experiencing this? Is this something I should call Blackstone about? Thanks in advance.
