Becoming a SNG Grinder

I am seriously thinking in becoming in a near future, a SNG grinder.
No doubt that i like to play more SNG's or MTT's than cash games, that is for sure. I want to take my SNG game to the next level.

Last month i grinded a lot of cash games, sometimes not rolled for some stakes. I did not break even, losing some buy ins. I was just chasing the silverstar status and i made it.
This month i have been really soft about the grindind, not poker, i am always committed to study and play. I am not grinding this month but i have some late nights by playing and studing Holdem.

I am still analysing the SNG's structures, wich one should i play more the turbos or the regulars? Wich players field, the 9s, the 18s, the 27s, the 45s, the 90s, the 180s? Heads up?
Still searching for answers and still analysing some professional poker SNG's grinders.

In the challenge to turn $100 in $10.000 Boku87 started playing the $1.10 turbos of 18s and 45s players.
Then after playing more than 600 of these he played the $2.20 180s and $3.25 45s SNG's turbos. Then after 120 games of these he mixed with the $3.40 18s SNG's.
Only after 340 games he started to play the $6.50 18s/45s SNG's and also the $12 45s SNG's. When playing this ones he also maintained the $2.20 180s SNG's.
After 360 games he started playing the $27 18s/45s SNG's mixing with the $12 45s and also including the $7.70 180s SNG's.

So you can see how many games he first played before moving up in stakes, usually only after 350 games. This is what i call bankroll management, only go up in stakes when properlly rolled for that level.
Besides Boku87 I am also analysing other guys and taking some conclusions, i play a lot better at SNG's than cash games, just defining my structure to play at. Btw, Boku87 plays only Turbos. The Turbos gives you a faster hourly win rate but also decreases your ROI. Posflop skills are for regular SNG's, Preflop and push or fold skills are for Turbos.
