I don't think the film was over-exposed, I used the aperture priority auto on my F80.

The original 10 x 8 were done by Monolab, and were "hand printed".

I later sent the negs to Club 35 for 12 x 8 's and they were nowhere near as grainy, but lost the nice contrasty feel to them as well.

I have since invested in a roll of Delta 100. Now, where did I put that monopod........
