I'm using the Ytex Pro Tour 16L in white color. I went to my local tennis shop and "felt up" all the poly strings there. That one seemed the softest in hand. I was a little concerned at first b/c the stringbed felt tinny and pingy the first 2 days but then that went away. If I end up not liking it, I'll bring the other half with me when I come up to DC and you can try it.
