Thanks everyone for your input. This discussion is very helpful.
I talked with the OMS folks. They said they would draft something up in the bigger board department. Ill post the pattern here for comment when it's done. Unfortunately they are quite busy right now with custom work, which is their mainstay, so not too sure when it will be ready.
OMS say the have several different patterns coming, including one that is just plated through holes with pads like that one.
@DirtBiker
You got it right. That's exactly what this particular board is for. Thanks for your oder too, it went out this morning.
You have the right idea too. That's what this shield is all about. Thanks for your observations too. Maybe the next time you need to stock up. I know one the ones OMS are planning has a similar pattern all the way from end to end, but with 4 holes joined on each side.

Please let us know what you think once your boards arrive.
Again, thanks everyone, I appreciate your input.
