..... I think i am gonna do a front master cylinder off the rear brake to run the front caliper to keep the bars clean...

..I am extremely curious how you plan on doing that setup...are you talking about "operating" both the rear drum and front disc from the rear break pedal?

The reason I was asking about the single pedal operating both breaks was at one point I was looking at doing the same thing....some people commented on the idea and I nixed it once someone brought up the idea of attempting to stop on different surfaces.
Having them proportioned for dry asphalt is fine if that is all you are going to ride but then that can easily change with a little wetness...
