i'm off to Chicago in a week and a half, and need to send one of my acoustic guitars back east beforehand so i have an instrument to play while i'm there. which is better, UPS or FedEx? by "better," i mean "less likely to turn the Blueridge BG160 into a collection of lovely sunburst toothpicks." and while we're about it, is the carton-inside-of-carton shipping method typical of, e.g., internet-purchased guitars sufficient, or would i be better put to ship it in the hard case with a carton over the case? i assume it'd cost an ungodly amount to ship it in the case, though?
