Hi guys. Could anyone please help with string tension recommendations for this racket (18x19 string pattern)? I have a (reputedly) soft multi that I would like to string with but I'm stuck on tension. I also have some cheap natural gut but will try that later on. This racket (LM Instinct) is new to me, been hitting with an M-Fil 300 strung with syn gut at about 54lbs. Much appreciated. TIA.
