To each their own regarding dry mounting, but I always refer back to the photography conservationist I had a conversation with. Her name is Patty Landres, and works/workes at the Minneapolis Institute of Arts. When I first started seriously photographing, and asked her advice for mounting my prints, she very assertively exclaimed the following: "Whatever you do, do NOT dry mount your photographs. Ever".
And then began to explain to me what a pain in the neck it is to try to save a print where something had happened to the board the print was mounted to. You may draw your own conclusions, but I don't think advice gets more expert than that.
