is that the tubes called dub dub?i never tryed them but i will say not all tubes r created the same spend the couple extra dollars get good ones .I fell in the fleabay trap of cheap now i have bunch crap tubes collecting dust :banghead:
I shot Thera-Tube many years ago. It was the old fat style of tubing with a heavy draw weight. The red version was easier to draw but didn't compare to the popular 1745, 1842, 2040, etc. I'm not sure what the current TB-tubes are like. I haven't seen them in years.
