All the replies are great suggestions. I happen to be on Staff with American Baitworks, so will suggest the Halo new HFX series. They replace the Black Widow series that is my current choice for frogs, and I have been Staff with Snag Proof since 1996, and have 4 dedicated frog rods, and throw frogs 24/7/365. Now, to speak brand agnostic, what you need depends on a few variables, including your height as well as the areas you fish. Also keep in mind, I am in South Florida, and fish Lake Okeechobee, the Everglades, etc. where heavy grass is EVERYWHERE. As an example:
Thick mats/superheavy cover= I use a 7'11" H with 80lb braid
General purpose/only frog rod= 7'3" H with 65lb braid
Open water/popping frogs= 7'3" MH with either 50lb or 65lb braid( I have both depending on cover near by)
If you are under 5'10" in height, drop back a size, like 7'6" instead of 7'11", 7' instead of 7'3" or 7'4"...you will find it makes control of your casting easier.
