Well, multiple rolls eliminates a problem I had once - I had some grit
caught in the felt light lock on the "mouth" of a film cannister. Do you
seem to get one long scratch, and is it at the same relative position
on the film (like sometimes you see on film in a movie projector?).
Are they pretty bad (like deep gouges) or more like barely visible?

Sometimes I had processing lab scratches, but they tend to come and
go, and be in different positions from one roll to the next (although
I'm not seen that much recently since I switched labs). 

I forget which camera you are using, but one thing I've done 
occasionally is to take a junk roll of film still in the cannister, and
run it thru the camera to mid - roll. Assuming that you can open the
camera back, then you can take a look at it to see how tight the tension
appears on the film (which probably won't be perfectly flat since the
pressure plate isn't in place) and whether there are any obvious
sharp bumps somewhere along the film path which might be making
scratches. Also, if you hold the camera up to your ear while you
move the film, you *might* hear the emulsion being scratched 
which would give you a clue as to when (advance or rewind?) and
where on the film patch the problem is occuring...

keep us posted!
