So for as long as I can remember, I have always used the traditional O Ring for my wacky rigged Senkos. I also use the traditional yellow plastic tool to put the O Rings on. Been seeing a lot of great reviews about the newest Wacky Rigging tool/pliers. Heres my question. I can get like 500 O Rings from a buddy of mine for like $20. Yes, I do lose my fair share of Senkos and just come back with the O Ring on the hook. Is it cheaper to use the shrink tube and those new plier kits, or just watched a video on youtube where he just used shrink tube, and it slid right on the senko w/o having to use a special set of pliers. Just heated the shrink tube up just a bit and good to go.
