Does anybody know off of the top of their head:
1)The most conducting metal
2)A conducting metal with the roughest surface (looking for surface area)

pure metal or composite?

Off the top of my head:

1) if your talking about metals and conducters, the classic answer would be copper, if you want to keep things simple stick with his.

2)Well if you take a metal solid it's 'roughness' is not really a property of the metal you choose, more how it's been worked.

Ze best conductor, she is silver, not copper.

Tom is correct, the pure metal with the highest conductivity is silver

The standard composite superconductor is NbTi (Niobi-Titanium) at 8K.

From Giacoletto:
@ 273 K
Ag (five 9s) 0.0147x10-6ohm.m
Ag ("normal") 0.0150
Cu (four 9s) 0.0158
Cu (O free, 99.95) 0.0153
Au (five 9s) 0.0219
(all in annealed condition --- cold working raises resistivity)

14-kt Au(cold worked) 0.0145
(annealed) 0.0150
