Mark,
I am not a frog expert but I do have confidence in it. I had my personal best day on a Spro frog a few months ago...5 fish/24.5 lbs. I am probably a little different in my set up than most but it works for me and am 100% confident. I fish a frog on pads, milfoil, and thick vegetation. I use a 7'6" Esox Heavy/Moderate Fast (76BA) or a 8' Powell (806CB) rod. The Heavy power rod helps me get the fish out of the mess he can get in. The Moderate Fast tip is the key to give it the right action and allow the fish enough time to engulf the bait before setting the hook like most reaction bites. I use 50 or 65 lb. Power Pro. I've tried Mono and heavy Fluoro but just don't have the confidence in it. I very seldom lose a fish with this set-up and when I do it's because he got wrapped up for too long and leveraged off. You may be able to get away with a MH rod in the pads. I would recommend trying the different rods and seeing which ones work best. Most people wouldn't hear of using a Moderate tipped rod but the rod has backbone because it's a Heavy power.
I will try different things and colors when approaching an area with a frog. Just slow reeling it over the top of the vegetation seems to work best but hopping or chugging it works in certain vegetation. I think this is one bait where color makes a big difference. If a fish hits it short, I will reel it in as fast as possible and cast it back to the same place and start over. I've had very few fish hit it again just by letting it sit there. Wait til you feel it before setting the hook and drive it home hard. Get the rod up and get him on top as fast as possible. I use a fairly fast reel (6.3:1 or faster) with a good drag cranked all the way down. If you think of anything else let me know. As far as baits go, Spro 65, Spro 60, and/or Spro Popping frog. The others are good but IMO just imitations of the Spro. It's worth the money.
