At that scale (250-300  miles edge to edge) I would think projection 
should not make much of a difference. Any map gurus care to comment...

Personally, I do not like the new maps they are putting under this 
radar. While at first glance it looks better, the sole purpose of the 
map in this case is to orient the user, and while the new map does 
this, I do not think it does it any better, while the additional eye 
candy makes it harder to sort out the radar data...
