I finally found my favorite string and that was regular Tour Bite 19g in a hybrid. Love it, but gave me hand tendonitis. Now will try Black Spiky Shark, Tour Bite Soft, 4G, and AlU Power. I think ALU Power is the stiffest of the 4, but like the power and consistency it brings. Any comments of the 4 here? I have been playing with Gut as my hand gets better, but lacks lots of control and spin. I love hybrid with better string maintenance and endurance.
