I haven't caught too may fish on the solid rubber frogs, mostly because I use other baits, specifically hollow frogs.
I've done a lot of hollow body frog fishing this year, and hadn't given much thought to why I had just a few Snag Proofs in my bag in years past. Here is what I came up with:
Snag Proof: all around good deal, good at weed/padless, good hookup ratio, durable
Scum Frog: softest body out there, and best hook up ratio, tears up easily, inexpensive
Spro: sublime action, tunable: cut one "leg" shorter than the other and you can walk the dog, body is too thick, you really have to wait to set the hook, lower hookup ratio, best colors, last forever, pricey
Furbit: flat out unbelievable when nothing else works, pricey
Basyrisky: they don't work, forget the name... :-X, actually, they are a different bait altogether, I like the smaller size
Scumfrog Bigfoot: another weirdo hybrid, club/paddle feet are great for going through open water, then pads all in one cast. I think this is the bait that replaces all the paddle tail plastic frogs for me.
