we are going to build in Dubuque, Iowa, where the humidity is relatively high, and we are wondering what an engineered hardwood floor would do in the summer-time. Will it "cup" like solid hardwood, or would we do just as well to get solid hardwood flooring. We are interested in Durafloors for the engineered flooring and Bellawood for the prefinished hardwood. We do not want Pergo or any laminates. So, which of the two would be best in that area? Would appreciate an opinion regarding this matter.
Thank you.

How about a floating hardwood???
