This was a long time ago so it's hard to say. But I've had plenty of reds that tasted great straight out of the bottle, so IMHO any wine that needs to "open up" is not as good as one that doesn't. Also, while it is absolutely true that the taste of a wine will change over the course of an evening, it's far from clear how much of this is due to the flavor of the wine changing and how much due to your perceptions changing. Taste buds can get fatigued (I get "wined out" after trying 5 or 6 different wines) and food makes a huge difference too.
My bottom line: I now know plenty of wines that reliably taste great (to me) straight out of the gate and keep tasting great through the whole bottle even if I keep it for a couple of days, and which cost a lot less than Silver Oak. So I just drink those :-)
