I have always been a hardcore Ovation fan. The action is one of the best I have found on an acoustic and the sound is outstanding. Temp. and humidity is something you have to worry about w/all guitars but with that being said, Ovations IMHO are one of the best for standing up to changes in temp and humidity.
