The guts of this is the blank action, spiral direction, the rate and length of twist needs to be matched and the current GT-R blanks have all been designed for either conventional Overhead or Spin, I am sure the GT-R blank would handle it but until we engineering a blank especially for sprial wrap I'm not going to risk producing a rod that looks good but dosen't function properly. Talking to a Norwegin rod builder who was making spiral wrap rods in his country many years ago, you need a minimum of 4 guides in the transition to get the action and loading distribution right, I showed him rods with 2 or 3 guides on the spiral which in his words, "zis is askin forz troubil at zum stage und you shouldn be pizzin round wiz shyt yuz knowz little aboutz, bezidz wez only developed it to makz it eszy forz personz whoz cant use a normil ozer head rodz uzerwiz all za rod manufacterz would haz made all zer ozer headz ziz way"
