Hi. Im currently using mgpmp. Before i strung it with kirschbaum supersmash 17 mains at 58 with psgd 17 crosses at 58. It felt very hard and stiff, and it made my elbow hurts a lot. So i decided to try a softer poly, PH at 56 mains with wilson extreme syngut 16 at 58. It still feels very hard, and only from 2 hours of practice im feeling my elbow sore. So now im gonna remove the strings and string it again, and i want you to recommend me what tension should i try. Thanks in advice.
