The general consensus on this topic (And it's been covered extensively by people that play them for a living) is that your going to get a greater return on your investment playing regular speed sit n go's. The return on your investment is definitely going to be smaller on turbo sng's....I seen a figure somewhere that said expect a 4 % drop in your returns if you play turbo but I'm sure it can vary....However, Turbo's do balance out if you are multi-tabling because they are over much faster. Assuming you play them both at the exact same level of skill....your going to have a higher hourly rate on the turbo's because they are faster. It's all a matter of preference. If you can multi table Turbo's successfully I think you can make money faster this way
