I agree that it does. I have been stringing with crosses 3 pounds lower and it works. I guess my concern is that with a poly main, id have to do something like 54/51 and just hope the crosses are not too powerful. I have been hitting very deep and too long so I'm trying to reign it in a hair, but I think the poly switched from the cross to the main may do that just fine.
So I will stay with the 3 pounds less on the crosses. I feel that it is the way to go with these racquets as you have read as well.
