Always seems to develop sites for your sponsors who's designs just seem to sell better?

I have to admit, over the years there have been several designers who have a unique design 'style' that i can always tell if they created a site for one of my sponsors, Mike from AAA Adult, Steve from ScorpioCreation, etc, etc.

I just wondered if anyone else specifically went out of their way to promoote a site that they knew who the designer was and, by knowing who designed the paysite, you sent traffic to the tour knowing it would sell?

Likewise, are there designers that if you know built a programs paysite tour, you wont send traffic to it because their style just doesnt work on your traffic?
