I'd keep the pieces to 3 or 4 on the flyrods. Just don't like too many joints, not even sure who makes a serious 8 piece flyrod. Normally a 4 piece will tie in with your tent, but it depends how long it is I guess.
Googled, and in a thread where a guy was being told not to get more than 4 pieces, someone mentioned Orvis makes a 7 piece, so I guess you could get one.
