Why the hell would you post a video of yourself playing untuned drums? What is the point?
Anyway, the smallest I would go for a kick would be a 20 inch. Small toms tuned low actually record really well. Even a 14 inch floor tom is fine. In recent years, it was hard to find kits at GC that had floor toms bigger than 14 inches. The racks were usually 10 and 12, with a 22 inch kick. They were also relatively shallow.
A far cry from the giant kits of the late 80's, where the toms were just as deep as they were around...
This ^^^^
I prefer larger drums, but my kit does double duty live and in the studio and I just like "classic" sized rock drums. A 20" kick would be the minimum, but you can go small-ish on the toms. If you had 10", 12" 14" toms tuned low like Farview mentioned, you'd be in good shape. If you want fat snare sounds....get a Supraphonic.
