In my case I'm looking trucking down a steep hill in either the bucket of my tractor (loose or in pails) or a UTV (pails or bags) then carrying another 50yds or so to a boat then spreading from there.

Pelletized lime in bags would probably be the most practical, but looking at around $200/ton as I recall. Then I still have the labor of spreading.

So long as there are no inherent risks (wild swings in PH etc) this seems like the solution for me.
