solid body should be ok . i had a classical that went through a really cold winter with me and the finish cracked on the front and sides, i guess that was due to the wood shrinking or whatever the cold does?
also i cant get it over to Australia from the uk as i think the flight would kill it (its handmade and very sensitive)
i know when winter hits here all i have to do is a little adgustment on the
truss rods usually and again the same in summer.
