Jimmy,
Regarding the size, number of drums, etc.. I have 2 sections, each 7 ft x 16 ft. At each end of a section, I used 3 drums, side by side. In the middle, I just put one on each side, lengthwise along the side. Each drum is 2 ft diameter x 4 ft tall. It's very stable, but will rock if a couple of people stand near the same corner, for example. I've had 4 adults and a couple of kids on the combined 2-piece, 32 ft long section. One thing that helps the stability is that it's linked together with galvanized pin hinges that I can remove if necessary. I just leave it connected and it's pretty stable for me. I haven't connected it permanently to the bank yet, so that would also make it more stable. I plan to do that in a way that allows me to pivot it left 0r right.
Hope that helps.
Dave
