Stud Hi Lo Tournies

[Zoroaster8]

I am a fairly successful at stud hilo ring, but am having trouble getting anywhere with tournies. Structure is one problem - even at a good site like PokerStars, by the 4th round, the betting levels are so high, you have to already have to have some chips to do anything it seems. (Never mind the ridiculous sites like PartyPoker where it is simply a crapshoot).

What do people think are the keys to success?

Intuitively, it seems you have to take more chances to accumulate chips early, but loose play in hilo is a presription for disaster in ring play...

Thanks.
