The Casinos that I had were always 'at home' guitars and were never played in a gigging situation where volume gets cranked up. I currently own a 339 and it's not heavy by any means but I have to say that I DO prefer the look of a full bodied 335.
My aging back can use a weight friendly guitar and I very much like the look of a 335 type guitar. The fact that they are full hollow body making them very light is one of the main reasons. I have had two Casinos in my guitar acquisition years but didn't hang on to them and now, Lord help me I find myself thinking about another.
