So I know that for treble hooks you usually want something more moderate so that it can take the pressure off those tiny little hooks.

For this reason, I have been using a 7' moderate action, MH Power Mojo Bass. It's their crankbait rod.

I mainly use topwaters such as Jitterbugs, small Pop-Rs, Spooks, Torpedos and things of that nature.

What would be the best rod Action for this?

Carlos

   6 1/2' medium

if you like the mojo rods try the topwater / jerkbait model its 6'6'' medium action with a fast tip I have one and it seems like it works well

I like a fast action for working topwater

mf for topwaters (and hard jerkbaits) here.

Medium power, mod-fast action.

I run all my treble baits on Med Mod or equivalent.  Two of my favorite rods happen to be Avids.  6'6" and the 7' med mod.

6 1/2' medium

X2  I used to lose a lot of fish using a 7' MH Spinnerbait Rod, but since then I have started throwing my spooks and Pop-Rs with a 6 1/2 ft Medium power with a moderate/fast tip.  Not to mention I have braid on my MH and 17lb mono on the M.  The stretch actually seems to make a difference for the little trebles to keep their grip.  The rods I have been using have been either Berkley Signature Series or the BPS Tourney.
