Black code 4s

It felt softer and spin was about the average, same as any other co-polys can give.

Excellent as always

Strung these as mains at 54 and NRG 2 in crosses at 52 (my typical stringing). Center hits are powerful and control is outstanding. I can generate whatever spin rate is appropriate, whether for a low deep shot or abrupt cross court winner. Off center hits lack power (compared to TF Black Code). I might try upping the string tensions next time. By the way, I've been a huge fan of TF for a long time so please forgive any apparent bias.
