on frogs such as spro and snagproof how do you trim the legs to get them to walk the best ?

come on guys help me out here,i have seen somewhere where you trim the rubber strand type legs 1/3 off or eliminate some of the strands to get the frog to walk better . maybe an earlier thread already covered this ? any help is appreciated. :question

on the spros, i cut on leg about 1 inch off and the other i cut about two inches off

that should do to get a good walking action

I leave roughly 1 1/2 inches on the legs. I also cut about 4-5 strands off each leg.
