Look up poster Stoneage, who created RacquetTune. I think you need to input the settings for Rip Control unless some other poster already measured the string factors and has it on their iPhone. Ask posters Mikeler or Power Player if they've used this string. My recollection says they have in the past.
Rip Control is a polyolefin multi-ribbon multifilament. It's more 'poly like' then your initial choice.
