ive seen on a few posters sinatures that they are using a multi as a main and a standard syn gut in the cross i.e psgd mains and gamma advantage crosses. i thought hybrids had poly mains and some form of syn gut or gut on the crosses? What effect does using multi-syn gut have? also, i know its in the wrong section. i broke the strings in my hps 6.1 about 2/3's up the head, i plan to add lead to 2 and 10 to move the sweetspot up. How much weight should i add to 2 and 10 and shoild i counterbalance with lead i n the handle?
