2/4 Big Blind...misplayed?

[mdob]

I like the flop. We don't have the immediate odds, but I think we can assume we'll make a BB if we hit one of our 5 outs on the turn, so this becomes a call.
I think the turn's very close. If we discount the 9s and 6s to 4 outs and say we'll win half the time the 4th diamond comes, that's 8 outs total. That's barely good enough immediate odds to call and I think we're taking reverse implied odds here.
