Bill, that's a lot of headstock that may not have the structural strength of the neck or a smaller headstock.  If you go with any bag, I would take a look at whatever you can do to create a stiffer backbone to protect it.

That's why I like the Bodyglove bags.  They are not really bags in the traditional sense, but rather hard case/bag hybrids with hard sides built into the bag.  
 
Bill, tgo

This thread is worthless without pics....Lol...
