not crazy about the pre-flop call without a really good read on this player, but not an awful play.

I prefer a call on that flop - keep him wondering and keep the pot under control. As muse explains though, the alternative is a valid play also. The thing about raising is that while you'll get many hands currently ahead of you to fold, the ones that call/re-raise make YOU chase. For example JJ with a diamond there will probably move all-in to your raise, but will slow-down after a call. The hands that may hesitate to re-raise you on that flop, will probably check-fold the turn anyhow, and you've risked less of your stack.
