Welcome to the forum! I have never had the opportunity to play a Dove, but based on what you say, it sounds like I really should try to find one.
Like Sal, I have both Martins and Gibsons, but the latter have the biggest piece of my heart. Also, I place myself firmly in the hack category, as far as playing skills. There is room for all here.
As for labels, at least today an orange label is for a limited edition or custom run guitar. A white label is for a standard production guitar. This is more of a designation for specification than it is some kind of quality stamp.
