Hi mike, I've seen your build on the Evo and by all the scratch building you have made I assume you know alot more than me... I'm planning to build a custom, fully scratchbuilt bicycle (Specialized Epic)... So I ask you:

Is soldering the best way to go?
What would be better (in ur opinion) Aluminum, Brass, or Copper tubbing?
I'll read further into the 'how to's' of soldering but just a quick one, can I solder Al to Brass, to Copper, etc? Can I solder anyone to anyone?
I'm not sure what version I'll make. What will decide this will be the ease of joining the tubes and how 'good' I can make it look prior to putty, primer, etc.. I'm thinking the carbon one would be better to hide the solder makes....

Here's the Carbon version


Regular alloy
