Here's a system I've been looking at over the past few days and has been very successful with each-way betting.

1) Top Unitab selection.
2) Pre-post fave.
3) Placed at last start.
4) 8 to 12 runners.

Today's selections are:
Geelong R5 no.10 - Nutopia
Geelong R8 no.2 - Sarenko
Dombeen R5 no.4 - Fat Possum
Balaklava R1 no.4 - Hellacious
Ascot R2 no.5 - Angelic Heart.
