According to http://creditboards.com/forums/index.php?autocom=creditpulls Discover IT tends to pull EQ.
I app'd for it this past Saturday and was approved. Immedietely saw the inquiry on only my EQ.
I say go for it then and let us know your results!
Well when I applied I had zero HP's on EQ, so that might have been a reason as to why I got a higher limit than my other cards.
Still waiting to get the card to see what my EQ FICO was. Should come today or tomorrow.
