i've been using pro hurricane tour 16 on this for about 6 months, i just thought pro hurricane tours were solid strings. but i was thinking of perhaps switching to a multi.. or a bit softer poly. right now i have these in stock, x-one biphase cyberblue SPPP i was thinking trying out x-one biphase first - it would be the first multi i would be putting on the pure drive team. i'm a 4.5 heavy server/heavy fore hand user that generally stays on the baseline.. i use a little topspin on the forehand for deeper shots, but i also need enough spni potential on the strings for the backhand and 2nd serves. so please, give me your input. 1) what should i try on first out of the 3 strings that i have? 2) what are some other strings i should definitely try out? thank you~!!
