I play with Babolat Hurricade 18g on a Ti.Radical MP so its an 18 x 20 string pattern. I use the 18g to get more spin but its hurting my arm so I want to go to a hybrid. What's cheapest and most durable non-poly 18g string I can use for my crosses that will soften up the feel a little? I was thinking of Prince Syntheic w/ duraflex 18g but I can't stand it when I break my crosses before my mains are even warn in and the reviews worry me. I am a former college 5.0 player so I hit pretty hard and with lots of spin if that helps at all.
