without asking additional questions ... i get mine strung two piece (4 knots) and i have only used hybrids so far. i do poly mains and multi crosses, but the reverse could be even better if you dont break strings. i usually string around 52 lbs
i have not tried full poly because i dont think my elbow can take the abuse. its a light frame and theres some recoil when youre hitting against someone with decent pace.
