The BEST PPD for Legit Tutorials

The files that I will use are made by myself and is perfectly legal. My question is, what PPD site should I go for? I'm currently choosing between FileIce/ShareCash/MgCash/UploadPay

Audience is 13-45 year old male and female.

Another question, will I earn more with content locking or PPD with this kind of files?

My visitors will be getting what they want after completing the offer.

Thank you very much for your inputs.
