Kyle:
I hear what you say -- but I'll rate ANY aspect of BM over BD. You can start with a straight match play comparison -- I'll be glad to break it down by hole groups (e.g. par-3's, par-4's, par-5's) or how the holes fall out when playing them in terms the overall flow/character of the land.
BM is quite walkable.
One final item -- the hazards and green complexes are also more intricate and far more stress producing for the shots you need to have within your portfolio.
You also dodged my point on BT - the middle stretch of holes is the real weak point of the course. Once you leave the short par-3 on the front until you get to the approach at the 13th the caliber of holes in that run is a good few steps behind the opening and closing ones, in my opinion.
I prefer BM to BD as well, but it's a closer contest for my part.
BM is technically walkable but, even as a devout gym rat in his late 20's, I'd prefer to ride there. I played the course in very comfortable weather (early March 2006), but the summer heat would make walking a foolish proposition. Plus, you'd have a tough time keeping up the pace of play if you're paired with riders.
Regarding Trails, I actually like a few of the "middle holes" at BT, including 6, 8, and 12.
7,9,10,11 are not at the same level as other holes on BT, but they're still far better than anything around my neighborhood.
