What should I be looking for in a good rod for plastic worm fishing?  I am leaning toward a medium power rod.  What would the difference be in a 6'6" rod vs a 7' rod?  

Thanks!

i use a g loomis bsr803  MH spinning rod that i love it's the best jig and worm rod i've ever used  ,the link is for the med action bsr 802 if you are looking for casting it would the bcr 802

Welcome aboard!

I fish a 7'  spinning rod, but there is really no fundamental difference.

Medium Power or MH Power/ Fast Action in a baitcaster or spinning rod

is all you need.

Either a Med or Med Heavy rod will work fine for worm fishing.....Now I like a 7' Med Heavy action rod for larger baits like 10" worms, gitzits, and jigs. I want a very sensitive rod b/c many times especially in colder water, the fish will just sort of pick up the bait off the bottom.

For smaller finesse worms with jigheads, floating worms, flukes, etc....I prefer a Med action rod with the same sensitivity requirements.

I personally like 7' rods but 6'6" will work just fine. I like the hook set on a 7 over a 6'6 but a the 6'6" is nice when fishing out of smaller boats and from the bank.

What they just said.^^^^^^^^

The biggest difference is that one is six inches longer.  With a 7' rod, you can potentially make longer casts compared to a 6'6".  That being said, a shorter rod will potentially be easier to make more accurate casts.  The more important factors are the power and action.   To me, an ideal plastics rod would be medium heavy power with an extra fast action.  If the rod is not powerful and the action too slow, it is much harder to set the hook.  If your set on the medium power, that's fine, just make sure the action in fast or extra fast.

I forgot to mention one other thing , the mossyback is extreeeeeeeemly sensitive.

For Shaky Head fishing specifically, do you guys prefer a stronger MH rod, or a more sensitive M?

I prefer Medium Power/ Fast Action. Lighter baits are easier to throw with a Medium Power rod.

Med. isn't more sensitive, it just bends more under the same load.

I love my St Croix 6'8" Avid spinning rod.

Medium power/Extra Fast action. Great hooksets

If you are looking for a weightless Senko rod, the GLoomis BCR893

is the best senko rod I have ever used, regardless of price.

"Bend", not "sensitivity". Action vs. Power. I do confuse the two.

More bend must equate to a better snap on the cast then. Makes sense now.
