who does this? does this help wiht not much tension lost because all my rackets have decreased in tension dramatically within a month or two! does this shorten the lifespan of the string? much help appreciated
IMHO, any string, prestretch or not, will lose tension after a month or two. Especially if you hit with it. If it's done gently, it shouldn't affect the string's lifespan. Just make sure you don't wrap it around an abrasive surface or something like a street lamp pole.
