I have 2 Babolat PD2012s. I've only played them with full beds of nat gut strung between 60-62# (which backs off to 54-56 after 1-2 weeks). I like that combo very much, but I am thinking about experimenting with a nat gut/poly hybrid. Could you please recommend a poly and appropriate tensions based on the current set-up I like (mentioned above)? From what I've read here, 4G holds its tension best. But what tension combo with the NG? Other recommendations welcome. Thanks!
