I dont really understand the concept of this PR trade thing.
I mean, if you send more traffic to traders, than they loose from not getting "high" PR, they will gain of it.
Thinking of SE traffic, that depends more on how good you are with keywords and structuring your site. I see so many TGPs focusing on PR and at the same time they have few words for the search engines. Also missing keywords in ALT and TITLE tags.
One of my sites has, according to google, "only" PR2, but still a lot of the keywords ends up in top10 on google. Even higher than the paysites.
Yeah, the SE traffic is nice, but dont let Google control your business. Quality is more important, and ranking dont account for this
