Go with whatever rod is comfortable. If a 7-6 feels too long, go with a 7. When I first started using rods longer then 6 or 6-6 it was awkward. But now, I only buy 7 ft and up.

If you want to use the same setup for topwater, don't use braid or fluorocarbon. They both sink. I think that would be a hard combo though. It depends on how thick the vegetation is you're fishing. If it's thick-thick, don't use less then 20 lb. But, I don't recommend using that same 20 lb for topwater. Get what I'm saying?

The braid will work for frogs, but the rod (depending on what you get) will probably be too stiff for other topwater. Some gear set-ups just can't be used for multiple situations effectively.

I hope that's not too confusing?
