I run with three also, mainly because of limited space. Here's what I have:
6'-6" MH Veritas / 6.4:1 Revo SX - Jigs, flipping (swimming, bladed, etc.)
7'-0" M Veritas Winch / 6.4:1 Revo SX - Cranking (Just got the winch. Love it so far).
6'-6" M Vendetta / 7:1 Revo STX - General use, no specific application. I actually like this setup for jerk baits.
I also have a 6'-6" M Vendetta spinning rod that I swap out with the casting version when I think I'll need to go lighter. It also works well for lighter jerk baits.
