Since you've given me such great responses on the corrugated sole question, here's another?

Is the Bronze option on the LN #4 worth the extra money? I'm replacing several planes over time as well as adding a few new #'s. I do like the look of the bronze, but it isn't offered with many of LN 's other planes so it is worth it for the #4? I do have a huimidity problem in the shop which I am working to eliminate.
