Babolat Tonic+ (BT7) break-in time?

[jacp]

Hi,
Just got Dunlop 100 4D Aerogel strung with Babolat Tonic+ (BT7) at 57lbs.
It feels really stiff, played for total of 2hrs, strung Jan 5. Because I never played with NG and racquet is new I am at a loss. So far I am not happy. Are strings going to loosen? I hit flat with very little spin.
I will appreciate your feedback.
Other sticks I use: Wilson PS 6.1 90 BLX, PK 5G, both strung with TF X-One 17H @ 52 & 62lbs respectively.
Thanx

I also had to go through a break in with babolat strings. their bt7 made their gut stiff. which i don't like. as all strings, it my loosen a bit when it comes out of the machine. however, the NG maintains it's tension after that.
I also play with a flat shot. I favor that rather than topspin. I believe that babolat's old natural gut is sent to wilson. If you want a pure gut, go for wilson. IMO
