Not new to this style leader. Started my dropper leaders to fish 3 flies, back in 1987! Over the years sold many 1000's. Even had the bright butt design back then. You would be surprised over the country how many state this style their design, improved, better knots, improved blood knots, with power swivel, etc. etc. I know where the design came from, since they needed samples, then went own way with what they call there design!
Many of these shops do no exist today. The ones that do, i remember!
State College would be a great example of Maxima hand tied leaders. I would bet our formulas match!
Simple design, dropper leader to fish 2 or 3 flies. Make it long, make it short add some color. dbl. surgeons, triple surgeons, blood, does it really matter that much. All 3 work! Go for something new not something that has been around, to be truthful, before me.
Many would say, never heard of him but I know better.
