Joe, I think your results are more the exception than the rule. I have been able to get down to 8mil traces with the Pulsar paper, and just as good with the HP Presentation paper.
The problem with the photosensitive steps is there are just too many chemicals and steps involved for it to be quick.
And, I agree with Harvey, run the board and paper sandwich through the laminator several (8-12) times then immediately into a warm water bath to release the paper from the toner.
The only real problem I had with the Pulsar was the stretch...I use a cnc mill to drill holes before laminating and the holes don't line up so well. Luckily the stretch is mostly in the long direction of the paper.
