Building a Bankroll For Newbies, SnG Version?

technically, you can't "build a bankroll" with SNG's because the most any site will give you back on your tourney fees is 100%. the reason low limit ring game whoring works is because there are bonus structures that pay you more than the attributed rake you give back to them.

I was thinking that SnGs could take advantage of the bonus whoring as well. One SnG = so many raked hands. Is this incorrect? Bonus whoring is definitely in my plans for building a bankroll. I had planned on following MrWookie's guidelines to a tee, just substituting low-level SnGs for low-level ring games? This not viable?
