Ok so I recently bought a huge lot of bass fishing equipment, and there were 2 crankin rods.  One was a david fritts perfect crank (7' MH and it says fast taper) and the other is a st. croix mojo bass crankbait rod (7' MH Moderate).  I only want to keep one rod for all around cranking (Squarebills, traps, and up to 6xd's).  So my question is, Which should I keep and which should I sell?

I'm in similar situation.

Have you handled them? The Fritts perfect crank is a composite rod and I'm assuming the Mojo is graphite as I'm not sure if they have a 7' MH in their glass line up. So, if that is the case, the Fritts cranking rod is going to be heavier in weight and if it was a pure glass rod I'd say you have to try it first but being it is a composite, it has a similar action as a graphite rod. Based on that, I'd opt for the lighter graphite if the actions are the same, no reason to use a heavier rod with the same flex as the graphite model. I have both graphite and glass cranking rods, my glass rod is for deep divers while the graphite goes for square bills and mid depth cranks but my glass rod has a connected feel that is different from graphite, it doesn't just bend in half and shut off like graphite or composite rods, instead as it flexes down the rod it begins to require more and more pressure to make the rod flex until it is solidly into the backbone and stops, it feels like you have endless power and it is only glass that will give that too you. I'd keep the Mojo and sell the Fritts, but both will work so if you like the Fritts rod you can keep it but both will have close to the same action so the lighter rod wins out in my world.

I really like my 70mhm Mojo. Also useful for super spooks and big jerkbaits (Pointer 128).

Mount a reel and run to some water ( or drive ) and throw baits on both rods.. That's how you are going to make the best determination.
