exactly - and as for the cracking and miosture exchangin stuff - this also depends very much on how the wood has been treated fomr the point where the tree was cut to the point where the instrument was built. Real good and expensive woods have been stored for AGES (in some cases over 100 years) in a special air condition. In italy for example there is a wood-stock very close to the shore that stores extremely old wood - the pores of that wood have been sealed by the salty air and the wood is almost completely dry - it won´t move an inch once worked into an instrument - thats what violin-manufacturers use for top quality instruments. you hardly see a violin with a crack in it unless someone jumped on it *LOL* - so i guess its not only a quesiton of treatment but also a question of the woods quality. So if you want to have a guitar that resists almost everything then you might want to consider geting one costum made from real old wood.
