These frogs come in 3 sizes 1 3/4", 2 1/2", or 2 5/8". They come in 8 colors, and I prefer the 500 Green Yellow and 503 Brown Black. When using these frogs you are usually in heavy cover, so I use a 7' heavy fast rod and a high speed reel with at least 30# braid.
I like to customize my frogs by trimming the legs a bit shorter to move easier across the weeds. To improve hook sets, try to wait 2-3 seconds before you set the hook in a upward motion with the rod. On slower days, try trimming one leg shorter than the other and it will glide and turn.
