I am investigating the change in size of pebble deposits over a coastal spit in my area and was wondering if there is any concrete theory on a relationship of the outer curve consisting of larger particles than the inner curve?

Well, this is a big subject. Generally on coastal spits the pebbles will be graded, however... It all depends on the angle of the spit too the prevailing winds and current (longshore drift). They will usually be graded largest to smallest along the outer curve depending on the prevailing weather / waves. Without knowing exactly where you are thinking of it os difficult to say exactly, but in general your hypothesis is correct though there is no concrete theory since they can almost all be disproved. Even longshore drift takes a bashing when you consider chesil beach (reverse grading compared too the prevailing weather).

I imagine that strength of currents on the outer and inner curves would make a difference, but it has been many years since I studied geology.

Study the World Heritage Coastline in Dorset in the UK there is a beach there where the pebbles go from large at one end to small at the other, and it is miles in length.

Dude, life's too short! There are plenty more pebbles on the beach
Sorry, I had to.

Yes, but I can't remember the name of the process.
Something about coastal drift.

only as much as the waves on either side of the oceans vary.
