i dont think you can ask about the big guys, a small linksite can give me just as much sales as a big one, i dont look at the traffic only, i look at: who will list me forever, then i look at the smaller linksites, reason? easy my experience has bin, the less sites in a linksites the more chanse i have to make a sale if i am listed at that LL............and yep i also submit to tommy if i make some stuff, if i make my list:
link-o-rama.com
richards-realm.com
penisbot.com
smutgremlin.com
wetplace.com
link-for-sex.com
and a bunch of my friends .com
damn i forgot tommy also, he sends alot of traffic, but i am honest, you drop of his ll after some time, still he send great traffic
