Melbourne GP - which stand?

[Waiter]

I'm looking to book Melbourne GP tickets shortly. Anyone been and can advise on best viewing positions?

I can get tickets for all 4 days in the Schumacher, Piquet, Fangio and Clark stands (different stand each day) but want to know where's best for watching the actual race. Is a different stand better or will a general admission ticket suffice? It's obviously cheaper (although the tickets are generally pretty good value, the 4-day grandstand ticket is about £175).

Any help much appreciated.
