Going to the WSOP Razz or Stud Hilo?

[stud7champ]

I am thinking of playing in the Razz or Stud Hilo WSOP tourney.
I have won a couple of Holdem Tourneys (In $100 buyin games in Vegas) and play a very comeptitive Omaha Hilo 5/10 game, for instance at the Mirage I was able to make a couple $100 playing very good players over a week period 8 - 12 hours a day. (Online I am weaker)
I have been playing the $10 & $30 sit and go Stud 7 tourneys on Party poker and normally out of 6 sit and my results are :
1st -1
2nd -3
3rd -2
4th or 5th -1
I seem to have on issues making it to the last 3 I have problems switching to playing more of the high hands when we are down to three.
Anyhow can anyone give me any advice on how to play better tournament Stud 7 particularly three handed. I have read all the books, Zee, Super Systems 1&2 and Championship stud by dr Max stern.
Thx
