bankroll game selection questions

[Rob121]

hi everyone. I am planning on starting to grind sitngos. I have a few questions i'd like to ask.
1. if I was to start with say $500 which level do you think I should start at? how about $1000?
2. any advice on which site has the softest games?
3. I consider myself a above average sitngo player as I understand the importance of "stealing" blinds late into the game. Do you think I should play turbos, how do they run compared to regular games?
