If liking polys but dreading the dead feel of it after several hours, why not just switch to Tecnifibre Bi-Phase at higher tensions (chose 17; better feel than the 16 or 18 )?
It usually snaps anyways before it dies out; way better than a dead string!
On occasions though when it breaks at the 10-minute marker and I only brought 3 racquets then it sucks because I have to borrow racquets from the opponent.
