Do you have a cap bank or some caps in your setup? There have been a few threads regarding modifications to help with cogging. Also I have a Quark 125b NIP that I am not using if you would like to move up. It is still brand new in the box. I just never got around to using it. I also have the RCM heatsink to go with it. There aren't many of them left around, but I know some people still love them.
