    Like the title said.
    Is co-poly more arm friendly ?

    Typically, they are more arm friendly, but the difference is the polymers used in the material. Co-polys include a mix of polyester and other poly blends, like PEEK and Polypropylenes to try to adjust the feel, performance, and durability of the string.

    Some co-polys are made from poly-ether instead of poly-ester

    In a big picture view, there isn't necessarily ANYTHING different about poly/co-poly.

    Before you all gather your pitchforks and come knocking on my door, we need to examine the terminology we're using. To a casual player, one NOT on TW, "poly" can refer to any monofilament polymer string. This includes "poly"ester as well as co-"poly"s.

    The reason this question exists is because people are imprecise with their terminology. This is only further muddied by people talking about 1/2/etc "generation" strings.

    So to be accurate in ANY definition, we have to lay out a few "ground rules" and context for the definition. In the context of TW, when discussing poly vs. co-poly, the term co-poly will most often be used when referring to a co-polymer string. Poly is more ambiguous (because it's being used as slang for any monofilament polymer string). However, you'll notice that poly is synonymous with polyester (also often referred to as a "gen 1 poly"). Co-poly in general is a more specific term than "poly" and is misused/abused less often.
