far and away my favorite frog rod is the He76HC. plenty of backbone with the perfect tip to walk a frog in open water. it isnt a true heavy action rod, so it really works a frog well. the 7'6" length combined with braid provides perfect hooksets on long casts.
My favorite Kistler for fishing both a hollow body frog (Spro or Snagproof style) or a Buzzfrog style is the AFJ71C. It has a great tip for both skipping and walking the bait and plenty of backbone for getting the fish out of heavy grass.
It is my favorite rod in the Argon series and is very versitile.
