In respect of HunkHunter, i found their traffic to be exceptional for the first couple of months then it slowly died out, although to be fair to Dennis, it was around the time when Google did their massive update and everyones traffic levels dropped and he also did a redesign too.

Unfortunately because of all those variables i cant say for certain if it was the copy i was using, the drop in Google traffic or the HH redesign that caused traffic/sales to die.
