Yeah, doesn’t do manual prestretch but he has a pretty nice full electronic gamma constant pull machine. He strings for Northwestern which is a big D1 tennis program. Machine has the CP you refer to but i truly don’t know if it is same as manual stretch or not. Anyway, a little prestretch is better then nothing Will see how long the playability lasts but if i get anything close to the 40 hours some people claim that would be amazing
I think you'll find that you may get to 40 hrs. The kevlar stays the same and doesn't really change, it's the cross string that gives up. Some people even just cut out the crosses and put in new ones and keep going (from what I've heard).
Would you be willing to try stringing the Kevlar Mains at mid-40s and Crosses at low to mid-50s, if you keep using the string hybrid? I ask as I find it crisp enough (yet comfortable) with this setup, and for that reason won't try 55 Mains and 45 Crosses (unless you tell me that you found that to be better).
