Your decision depends on who you are promoting, and how you promote them. I almost always prefer the % payout option. In my opinion, if I just wanted to make a one time bounty, go into marketing non-adult mainstream websites.

For me, I'd rather not just rely on getting paid for new signups. Last month Google dropped me from a number of significant rankings, and so what carried me through were my rebills and residuals.

Some programs may just not sell past 30 days for their customers. But, for example, say Naked Sword, Falcon or DirtyBoyVideo, who for me retain their customers in high proportions, I'd be crazy to just take the bounty and run.
