What material for brake lines?

[VSchus8282@aol.com]

I am about ready to purchase and install brake lines in a 65 MGB. After
looking through VB and Moss catalogs I am uncertain what to purchase. Moss
lists nickel and copper brake lines, VB list steel lines. Which are p roper
for a 65 MGB? Which are easier to install? Which works, lasts better?

Thanks for any help, 
Vic
