Well, you are rolled for that limit, and if you think you might not be then maybe that's your mind's way of saying these thing's aren't as worth while as they seem. It's not tough to beat when you run well and you have just over 45 buy-ins, so it would take a gang of suckouts to do too much damage to your roll, but it is possible, believe me lol. If you must play these then TAG all the way and I do mean tight!
With that said, you think you might consider playing in some 27person MTT's? I've had some great experiences with these games in the past and think you'd be better off building a roll this way until you can play in cash games where people respect your raises and you can play some real poker.
Get 1st place once in these MTTs and it makes up for 10 suckouts/entries. However if you're consistently making the final table (which is really not difficult) then you can expect to cash a hell of a lot more often than that unless the card gods are crapping all over you. Even then, you can steal blinds and win 1st.
If you get sucked out on in these DON's 10 times you would need to win 10 to get even and then tilt control would be a factor. I dunno I'd leave them alone even though 5th place counts as 1st place, it's simplicity is very deceptive to me.
