Sorry Chris. I just saw your post. Haven't been to this board in a while. Yes, I do feel that I can carry a bit more in the PBK Ultimate than the LE LT. I like the fact that the side bottle pockets are so large and deep I can stuff other things in there besides bottles. I can fit two skinny Dr. Browns in each pocket but never need to carry 4 bottles- so I end up stuffing other things in the other pocket. One thing I should mention though that BUGS me about this bag is the padding on the strap. It always flips around and bunches up. Other than that, I still really like the bag.
