Just passed 6, will start on 7 early next year.

Any recommendation on what material I should use?

TIA? CF? Rising Fellow?

A lot of people have been saying the CF/RF combo is the way to go. I'm sticking with TIA since for 5, 6, and 8 I only used TIA and it worked well for all 3.

Is this the CF/RF combo? Would it be sufficient to use it as the only material?
