Hello, I've decided to get some LaBella flats for my upcoming fretless bass, but I have this doubt that's driving me crazy. The bass is a 35" neckthrough. Now, when I'm selecting my options on bassstringonline for the strings I'm buying, I'm presented with this scenario: 34" Long Scale - 37" Winding Extra Long Scale - 38" Winding It's my first time using a longer scale bass, and this is probably confusing me much more than it should, but I just don't know which of the two is the right one to pick, and I don't want to mess up. So, which should I get? Thanks in advance!
