There are so many generic brand synthetic $3-4 guts out there and I'm not really sure which one to try. I'm looking for tension maintanence and playability in a 17g. String durability isnt that big of a problem because I use a 18 x 20 racquet. Can TW recommend me some strings that they have previously used before? Head Synthetic Gut, Gosen Sheep Mico, Gosen Super SHeep Micro, Prince Syn Gut w/ or w/o duraflex, Forten Syn Gut, Klip Syn gut, Gamma Syn. Gut, etc.
