What I think is one of the bad points of your regular dreadnought guitar is the sheer quantity of bracing near the sound hole... Since the sound hole is right in the middle of the guitar, scrapping any structural integrity, it needs all the bracing else it wouldn't work...
Then, what about ovations? By placing the soundhole nearer to the sides of the guitar, there's no need to brace them at ALL... Here's one of their bracing patterns:
Also, that's without talking about the Adamas line... Carbon replaces wood for the top leaving with almost NO need for braces while reducing the top's weight and size... Plurists won't like the idea of not having wood, but still... I guess that if poeple actually buy those at their 2k$ price point, they must be at least somewhat good lol
