Andy, thought I'd bump this for you.

BTW, I'm getting a couple of new bars soon (ordered yesterday) hopefully both Japanese Tsumura's (branded as Carlton, although the new Carlton bars are made in Germany)

They have the reputation of being extremely straight, strong, long wearing and uniform in the rails. They also use two sizes for the replaceable nose, one for 0.050" and 0.058" gauge chain, and another for 0.063" unlike most other manufacturers using a single gauge (0.063") nose for all gauges.
Oh, and they are polished and clearcoated
