Pay Per Download or Pay Per Sale? Which Filehosting to go?

[etui342]

Now, for almost all the filehosting service i have a registered account there but now my problem is i don't know which one to go and which earning mode to go.

my situation is, i have some files that are certainly very high quality and demanding for a
particular community of "porn hunters", and I am pretty sure that those files could not be found
anywhere on the web (at least not in any kinds of mainstream forums or search engines etc)

I don't worry if those files won't bring lots of downloads and traffic for me at the very beginning, but i am sure that within a week these files would be spread and other competitors will ''steal'' my files and share the files for their own profits.

I know there will be lots of traffic for the files, PPD should sound good but the amount of download will not be as much as the result generated when you search on "lady gaga" or "sex" on the google that just PPD will earn you an automobile.
I very much love these files and i am not so generous to share these files and my efforts for free. If I use PPD i may miss a lot of chance of sales. But if I use PPS but finally get no or very few sales it just sucks.

If you were me, what would you do in this situation?
