Currently I have a LM Radical with a complete ALU Power 16L job at 65lbs. I've been using the ALU for a while now, in my previous Head I Prestige as well, and have never broke them. I am purchasing a Head LiquidMetal Radical Tour from TW, and I'm going to string the mains with ALU Power Rough 16L, but I want to try something different on the crosses like a VS. Natural Gut 17 because I've been told this hybrid is one of the best in terms of playability . I don't play as much so I don't need the super pricey VS. Natural, but I would like to get something comparable (preferably less expensive). What is a good substitute? Another quick question, I usually string the mains at 65lbs with the ALU and the recommended is 62lbs on my LM Radical. Recently someone told me that since the ALU is such a rigid string I shouldn't string it above recommended racquet tension because it can do damage to my racquet . . . Should I worry? Thanks for the help!
