I'll order some online every now and then. For some reason they sell snuff in Europe and not snus(dip) and in the states it's the opposite.
Snuff is quite invigorating, like snorting a cup of coffee or something. It also makes everything smell nice for a long time as it's scented like fruits and perfume. Of course there's the sneezing and brown boogers too though.
I think How To Train Your Dragon was basically a documentary about this. I'd recommend sizing yourself similarly. You'd want to make sure you didn't bog down the maneuverability. I'd probably think GI Joe sized, possibly up to a barbie.
