ok ill answer what i do
1. i use all offer : PPL , PPS , RevShare
2. use both title and watermark.
3. dont know how many video, but totally its about 3000+ video in this week.
4. i use redirect domain to their offer. i not have tubesite, so if u ask wich one i recommend, i really dont know

i just do domain redirect.
about question point 1 and point 4. :
i use unique domain every offer program. example : offer from exposedwebcams have PPL and PPS offer so i use domaincam1.com for PPL and domaincam2.com for PPS
totally now i use about 15 domain.
