Here's a tip I've found useful-
An excellent way to learn how to bid is to look at the results from last month.
You can see exactly how every pilot bid and what they got as a result.

I would agree with the previous post about simplicity. The simpler bids tend to do well. Study the resaons reports and the wide reports. You'll be amazed how many guys screw themselves with complex bids.
