I recently bought a couple of these and was hoping someone knew the official stringing instructions, particularly if there was a two piece recommendation. Looking at the current stringing, it is one piece with crosses strung bottom up. Given these are 15 years old and in 7/10 condition I'd rather not put any undue stress on them but want to follow the proper instructions. If you know the proper instructions, one or two piece, or have any suggestions for string choice if you've played with these, I'd appreciate it. Thanks!
