Comments: I strung my racquet at 48 lbs, using the Lendl pattern (where the last 3 rows at all 4 edges of the
stringbed are done in syngut, to soften the shock when you hit there, but the center is all poly). The sweet spot has more feel to it
than even most co-poly strings I've used, and yet there is still that immovable poly character when you really whack it. After
experimenting with a sharp edged string, I've settled on this poly as clearly preferable to me, though it doesn't bite the ball as
sharply as the edgy string did.
