17 and 18 gauge multifilaments work well.
Prince Premier Attack 17 should fit the bill. Others to consider are Ashaway Ultrakill/Dynamite and Isospeed Classic.
LightningXX 17 is more durable but less feel/comfort than the multis.
Racquetball and squash strings are quite similar, usually thin, soft and powerful.
Many strings that are too powerful and/or fragile at tennis tensions do just fine in the 20's or 30's for squash and racquetball.
Neos 1000, Eagnas Combo 810
