The reason why I recommended Chris Rempels report is that he didn't bloat it with useless stuff.
Quite often you find pages and pages with example keyword lists the author found when doing keyword research. Chris shows a logical approach to come up with keywords that are more likely to result in sales than others.
He also talks about differences in conversion strategies for affiliate promotions and own product promotions.
These are only two things that came to mind without referring to the pdf.
All in all, I found a lot of useful stuff in there that I didn't find in other reports. IMHO, money well spent.
