Is a heat shrink tube better than using an o-ring? I have been using o-rings and they work really well, I get about 6-7 bass on average per senko rather than 2 or so without the o-ring. But I was wondering if the heat shrink tubes are better since the hook goes in perpendicular etc. How does it work? Because if the hook is going through the worm anyway then how does the tube help conserve the worm? Does it last as long as it will with an o-ring? And will the tube slide up and off the hook and onto the line when a fish is on just like an o-ring?
