Well then question is really, do you want to play a good game, or gamble more. You cannot take too much experience from 2 tourneys, where if you play 100+ tourneys for same money you will get that bonus experience. I do understand what do you mean, after I win SNG with buy-in $0.25, I want to go to higher limits. But time after time it has proven itself as terrible idea ;D Don't get blinded by potential prize, that way you can't play your best game. No offence, but if you are a great player, why this thread?
Variance is a bitch. And also you put yourself in very difficult position to make right decisions, you'll always have a huge additional pressure if you play your last money, and I believe it will affect your game aswell. BRM is there for a reason. Good luck bro!
