I would like some recommendations regarding string tension for hybrid jobs. I have used NRG2, Excel premium and more recently prince syn gut #17. My racquet (a PD+) is strung at 58 pounds and I feel very confortable with it. I just purchased some Alu power fluoro and gut strings to try out. What tension do you recommend of both mains and crossed thinking that I intend to place the Alu's on the mains and the softer string on the crosses. Should I install the gut, NRG or the Prince on the crosses? Thank you in advance for your response!
