Trying to decide between these two choices. What are the differences in these strings. Monot Super Poly says it's Co-polyester construction. Original says it's Co-polymer (nylon) + Fluocarbon resin. I'm looking for a great Poly string for hybrids and have heard great things about Luxilon's line. I'm confused which to buy. What is the difference of Co-Poly and Co-Polymer? Are both considered Poly strings. I'm confused what Lux to buy. The price differences are huge. I string my own and I don't worry about the arm problems some of these have.
