I agree Mike, the only time I use that little substraight is in my "bare bottom" tanks, I still add a thin layer, easy to clean and the fry don't get lost, but I think the adults are more comfortable.
Plus I also have the advantage of having my syphon hose from my 2 upstairs fishrooms threaded threw the floor and down into the basement, where it drains into a bucket before over flowing into the drains. When I didnt have that bonus, I would always vacuum my sand tanks into a bucket, man what a pain that was.
