Welcome aboard! I highly recommend Grizzly Jig. If you have time its worth the visit to the store! Great guys and will help in anyway they can! If not visit their web page. Not sure they carry spyderloc holders yet but have a great selection of other brands. Picture of boat or info of what you are trying to do would help. Yes get in touch with Creekslick. He pulls jigs and cranks mostly on the Greers which is a different style of fishing than slow trolling aka spider rigging. Hope I could help?
