do i promote with senuke my main money site or sub-sites?

hi
if i use senuke, do i promote my main money site domain.com or do i create sub-sites (blogspot, squidoo lens, ...) and
i run the campains for every sub-site (called tier-2, true?)?

the site i would rank is an adult tube site (microsite, only 20 videos), 8 moths old, 200 visitors / day from search engines.

or do you have better ideas to rank?

i wish to use seo tools, because i will rank 4-5 moneysites (already created) same time.
if i bought seo services, it will be very expensive.

sorry for my english
