String tension for copoly: What do you use?

    To the original question, I've tried dozens of combinations and prefer most polys at 47/45. This seems to be the natural elongation of this string material. Any looser and it feels like a plastic flyswatter. Any tighter and it feels like a board.

    A few other notables:
    -I find poly never works in a head size <95 (too stiff).
    -It never works in an 18x20 frame (too stiff).
    -It only works in 18 gauge (<1.20mm), otherwise it's too stiff. The thin gauge isn't a problem because poly rarely breaks, it just dies and then feels like a flyswatter.
    -I get around 2 weeks of play (3 sessions/week) before the poly dies.
    -I use RacquetTune as well, and find the string is dead when it has lost 15-20% of its original tension. Don't forget to measure the string factor of every new string size/type so that RacquetTune can accurately measure the tension.

          RacquetTune works like a charm.
