Old wifes tale, tighen the point and they won't come loose. Leave the tip loose and they will come loose if done even right hand LOL. Been building and shooting left helical for 27 years at the shop I work at and never a problem.With left helical it spins the arrow so that it MIGHT loosen the threads on points.
LOL explain to me how in the world you can see how they spin in each direction when shot????????????? Either you have the best eyesight in the world or a slow motion camera LOL.Explain this please. I'm a righty,and every shot I take, the cock feather (vane) rolls left. I noticed this last year while blank baling and I just went outside and fired off a few rounds just to make sure. My vanes are offset to the right. Even with QS's they go left before going back to the right down range. Makes me wonder how much accuracy I've (we) been losing before our arrows "straighten up and fly right.":mg:
