smalljaw-
Your posts are informative and detailed and i do enjoy reading most of them.That stated,your adamant convictions concerning reduced snag river jigs is incorrect and compels me into this response.
. Football jigs w/out a flexible wire guard,placed on the correct angle, are snag masters.Open hooked ball jigs are snag masters.There are jig heads that do stand up-BUT-you just have to spend the $ on custom molds to produce them w/ a complete understanding of plastics and wire diameter/weight and length of hooks.. That fact separates reality from conjecture.I'll not enter into a discussion again w/you concerning stand-up jig heads,design and central balance.- we tried that before.
BTW-layered,river ledge rock is the enemy for jigs.. The wider the jig head,the more snags you'll experience-regardless of the hook used.
.I'll refrain from going into a lengthy discussion detailing the effectiveness of single and dual ,flexible wire guards- concerning hooking ability,balance,durability and snag resistance . I spent 5 years and a tidy sum of $ developing and refining a complete line of reduce snag jigs for all types of bottom environments in rivers and lakes.. That doesn't make me better then anyone,just more experienced and accurate when I state performance facts.
Remember- i fish the same rivers you do and so do my customers-which- have the final say.
