I don’t know what site he gets his from, and if there is a difference in rigid ness , he makes the best football head jigs I’ve ever seen and sells them for over 6$ a piece so I believe him, I stopped messing with weedgaurds, but the next batch I make I’ll use this and let y’all know.... and also, he isn’t slipping the tubing over weed guard, he puts it in the weed guard hole and keeps it there from when he pours the lead to the very last step which is pull the tubing out and put weed guard in....
