Spot on Rabbitz. Some guitar shapes are horrors to play due to the way they are balanced (or not) with flying V being the most obvious and Explorers with a big rear wing section that tends to want to fall forward if you are inclined to doing acrobatics on stage. Adding mass can also increase weight which can be tiring when playing live.....reminds me of my Ric 4001 which was a large body that weighed plenty and I was exhausted at the end of most gigs.
