I'm thinking about building a 4-string for my personal use. I'll make most of it out of off the shelf parts mainly from either Warmoth or USACG. My question is this... when comparing a 4-in-a-row style vs a 2x2 style... does either design have a distinct advantage? The only thing I can think of is the angled 2x2 design doesn't require a string retainer, although I'm not sure why that would be an advantage. From a comfort standpoint, either design is good for me. Does it all come down to visual preference or is there something else to consider? Anyone care to weigh in on this?
