I have 4G 1.25 in one frame and have been trying different crosses in the other (matched for weight, balance, and SW).
I like various aspects of other poly crosses. Some offer a little more comfort. Others a little more spin. But none have offered the whole package: extraordinary control, great comfort, solid spin potential, and the best durability of any poly I've tried as a cross. I just keep coming back to my frame with 4G crosses as the reliable, confidence inspiring weapon of choice. Hitting flat or with spin I feel like I can "trust my strokes" more with 4G in the crosses.
Only on Talk Tennis can you find people who believe
that 10 feet of lead tape has no effect on a frame...
