Mostly hiking for sure.
Then I'd suggest a light weight wood field.
The Toyo 45CF presents a nice compromise however. Made of super tough carbon fiber, it shares some design characteristics (it is self casing!) with the heavy metal Toyo field cameras but has the very nice light weight that is characteristic of wood field.
The Canham DLC45 is at the other extreme. It is a super capable, light weight metal field camera of unique design.
