Which pros use Natural gut, and at what tension? I heard safin uses all gut strung at 66lbs, and Federer used to use All gut strung at 54!??!? How can federer string gut so low, since gut is supposed to be a very powerful string?! I dont know how it plays at any tension, so i cant complain. I'm looking to try a full gut job for the first time, and im wondering which end of the spectrum in terms of tension i should use first. Im a 17 year old junior player using an ncode six-one 95. Feedback is appreciated. Before this i used Ashaway monogut in tensions ranging from 53 to 62, experimenting with it. Its nice but im tempted to try gut with string savers of course..
