General concensus is that the stuff sucks! Both for manufacturing and personal use. Just being honest from both talking to dozens of people and reading. I have not used it, but it was big talk for a long time when the 3X stuff came out.
A lot of guys are really taken back by the 3X stuff when they 1st see it. But I don't know a single person in the club I fish in that has ever continued to use any of the 3X products after trying them!
Sure it stretches and doesn't tear, but it also causes more lost fish than a dull hook. Skin hooking is next to impossible, and it is the stickiest plastic in the world!!! Everything sticks to it, and it sticks to everything else! Forget about flipping or fishing near timber! What ever you do, don't let your bait touch the ground. You'll spend the next 15 minutes trying to pick rocks off of your bait instead of fishing!
