I received my GB Pro Top bar from Jeff today, I also got the GB rim and drum as well as a chain from him. The bar looks great and I hope to give it a workout this weekend. I had to have him order it, it is an odd ball I know most of you prefer the .050 but I had him send me the .063 24" bar to stay stock size with Stihl. I can say one thing, that 24" bar seems to fit that 046 mag allot nicer than the 32" it came with and makes it allot more balanced.
