Generally speaking, the cheapest and highest converting clicks will be the brand terms of the advertisers you're promoting. However, they usually don't allow affiliates to do this.
IF I was wanting to get around this, I would just daypart while people are out of the office. To be even safer, when most people are sleeping. Usually it is someones job in-house at the advertiser to periodically check these terms but they only do it when they're in the office.
If you get caught, you could get dropped, FYI. It also helps to make sure you're masking the keyword it is coming from. You'd feel dumb if they could see from your traffic that you were bidding on their brand terms.
