Michaelg, just be careful with exotics. They are worthwhile in the bigger meetings but for those country meetings you can seriously affect you odds.

For example Kembla Range 2
The Quinalla had 3883 cash in the pool. Assuming it paid out 85% that will be $3300. It paid out $74.20 That means there were approx 45 winners.
You become winner 46. That drops the odds to $71.70

Thats only if you bet $1 on it. If you bet $10 on it then the odds would drop to $60. this stops you scaling it up with more money. And it might even be enough at minimum stakes to drop too many odds and result in a loss.
