Sorry ali I was just saying that it is not a different racket so essentially if you weighted it with lead similarly to say hewitt's lay up you would have a very similar bat. So if he is stringing at 38 lbs then you would have an understanding of what that feels like.
I don't see this bat as being any more powerful than my legends/melbournes and I string them around 49lbs. My coach strings his n95 low 30's he doesn't have any problems.
Get one, give it a go
