Arjonius, better idea would be just sticking to one type or tourney and slowly building it up, that way you'd last longer with your money. (besides, if i'ts for the entertainment that you play, it won't matter if you play the lower buy-in one or the higher buyin one)
atleast if you keep it at a certain level all the time, your bankroll will be heading upwards, and not down
if money is not an issue, bleh, just keep playing the way you feel like it.
as for me money is tight matter so i have to work on my budgeting
I mostly play 0.1/0.25 ring games or 0.25/0.50 ring games.
ring games i seem to play better, but lose more as well. (my personal excuse is that everytime i'm in a really big pot, i am ahead in the hand until the river card... but nobody seems to believe me)
before i got into ring games i played Sitngo's, I'd have streaks of good finishes but then i'd have streaks of bad finishes (again, i know i was better than them and i had the better hand but they got lucky on the river! my excuse..)
when it comes to large tourneys i tend not to spend more than 5 dollar as buy-in since large tourneys can be very hard to manage your bankroll with...
