Efficient Munar Orbit for mining?

[Ghostshark27]

So I'm using both Kethane and Extraplanetary Launchpads mods, and I'm planning on building a construction yard over the Mun. I'm trying to figure out the most efficient way to bring materials up from the surface to the yard. I'm debating whether to make it a zero inclination and have all my supply ships burn for the equator, or set the construction yard at a higher inclination so that it can pass over more real estate. The way I see it, with zero inclination, I can launch my supply craft anytime and link up, but with a high inclination orbit, my windows will be limited. Any help would be appreciated...
