Bigger lists will send alot of traffic which can be more productive, but do not forget about the smaller lists. I started doing that and my sales did suffered. Free traffic from any list can be productive, so use it. It takes next to no time to mirror a site properly and submit to the smaller ones. Very important for those who are starting out.
Plus some smaller lists, like myself, will feed our lists with traffic. Sometimes quantity(traffic brokers) so I show up in your stats but mostly it is quality(search engine ppc) because I need the sales too. Which can only benefit those few special people that submit to mine as well.
