the conversion kit from tfo is for double overhand casting.. not to burst your bubble. but i had a few friuends looking into this kit and it seemed she dotn spey cast all too great. i could check out some "switch" lines.. beulah makes one in teh elixer series.. rio makes some afs heads as low as 320 i believe maybe 340.. still may be a littl too heavy.... back too the double overhand conversion kit.. i could see it twisting on you a bit but taping the ferrals would eliminate that...good luck on your search for a line too match the rod.. but ive bin loving the beulah elixer for my 11'2" 7wt loop opti switch( i mean one/double hander), thinking about going too a loop custom head in the future... so i can chop it back and get it perfect!
