7' rod for party boat tuna

I'm with Mike. If you are PB fishing for tuna, 7 or even a couple of inches longer is helpful to clear the hull, which is a major reason for lost fish on PB.
I started out with 6' Calstar and moved up to 7' UC viper and find the extra length really helpful.
As far as longer rods giving better leverage to fish, it doesn't matter as I rail the rod and crank away and it's game over.
I say go with 7" blank, Fuji HB guides, and a rail friendly foregrip and you'd be all set.
I'm sure Mike can set you up with that very nicely.
