I have access to a few old pallets that I want to make into structure. Any suggestions on the most effective way to orient them in the water. Does vertical or horizontal make a difference? I was thinking about just tying a cinder block to one corner and a jug in the opposite corner so that it would be vertical, but then I thought that tying four equal-length ropes from each corner to the block would get it to be horizontal, and the fish might prefer to hang under the pallet rather than just around it. Any thoughts on this?

Also, anyone have a rule of thumb on how much weight you need to pull down a quantity of brush or wood? Can a 25 pound block hold down 25 pounds of cut tree or pallet wood? Is a 1:1 ratio OK, or can I use less weight?

Thanks for your helpful comments!
