You have a large mount husky bar for the .063? Is the square that much faster than a good round filed in the hardwoods that we have?
I've got 3 bars that can fit huskys in .063. None of them are short though. I'm working on getting a short bar to run with a 9 pin. The shortest is a 28" carlton right now. I've got a 30" cannon and a 32" oregon reduced weight in stihl mount but have the adapter to run on huskys.
