I've migrated to 4 Stomps/4 Snaps as well, stomps on top, snaps on bottom. It is certainly adequate, especially when you incorporate a few things on switches accessible in Stomp mode just one click away. The thing that leaves it lacking for me is the wasted real estate. Most of my patches have just two or three snaps, the rest is handled with the stomps. That leaves one or two footswitches wasted as they are allocated to snaps that I don't have. I think the ability to assign snaps to footswitches in Stomp mode would be the ultimate. I started an Ideascale topic on it, vote it on up if you're of like-mind!
