if you come up short and can't find a board you might consult with sk grimes ...
adam might be able to make you a board ( or has some in stock? )
and he is a short drive off of 95 >> 295>> woonsocket >> back on 295>>95 afterwards ...
you might also consider keeping your low profile, smaller, easier to pack/hike with
lensboards you already have, he ( adam ) can probably make you an adapter
that will fit your new 8x10 camera so you don't need to buy all new
lensboards, but use what you already have mounted ... on more than one camera
... removing lenses and mounting lenses on different boards every-time you want to
change formats is a PITA ... ... adapters aren't too expensive, worth every penny ..
and adam is an artist in every sense of the word
have fun in scotland
