Those would definitely work, but you would have to carry your bucket separately, (which some people do anyway). I know the larger ones such as mine take up a bit more space, but it is worth it to me because it holds my armor, bucket, blaster, boots, and accessories all in one place. The tray is cool because before suiting up, I take it out of the bin, extend the carrying handle, and it sets right inside for easy access to my gloves, neck seal, repair kit, etc., without having to set it on the ground. It also has a built in lock. I keep the key in a tiny key box attached with Velcro to the inside of my chest plate.
