Bert, I think the braces serve another function!! They strengthen the soundboard so it can withstand the tension of the strings. You can wind up with a buckled top and other horrors if you use strings too heavy for the bracing.Martin experimented with a lighter bracing; but the guitars using it require that light strings be used.
Mick. I would be interested in veiws on cases. Especially ones that allow you to carry your instrument on your back and still offer more protection than a gigbag.
