Go with whatever feels good to you.I prefer a Heavy/Fast for frogging.I haven't fished the MH Shock to say is not a good frog stick.However,the key words are FOR HIM.Just because he likes it for the application doesn't mean you will to.Go to the store and play with some rods.Bring your reel with you as well to see how it balances with different rods.
Even the MH Shock has more of a moderate action?
