8x10 is a great format to learn on!
Backpacking any distance will be a real challenge, as everything 8x10 is heavier and bulkier.
Color 8x10 is prohibitvely expensive( and if you'll be able to find color 8x10 film at all is very much a crap shoot!)
Nothing IMHO beats an 8x10 B&W contact print, however (unless its a 11x14 or larger contact print!)
I mention all this not discourage you, but so you'll be aware of the limitations.
