ALL the acrylics work fine. The real difference is the light source. One is Blue, and ALL the rest are UV. TUFFLEYE is blue light. WEAR EYE PROTECTION! FLEYE FOILS are highly reflective. I've used them all and Tuffleye is what I prefer. The FLEX is my favorite. You guys can use whatever you want. But just use it safely. Remember that UV is cumulative. It builds with the more exposure you get. If you wear sunglasses while tying or other protective eyewear, you can eliminate that from happening. Think also of the young kids standing around your tying table watching you tie with UV. Get them away from that light source till you are finished. Even wear protective gloves if you can. UV is dangerous stuff, you hear about it from time to time on the news. Proof enough.
AND............. EPOXY still works fine! Open a window and have at it!
