Just improved my rear bag. The DR. Bag by Protector.

The heavy sand makes things stay still. Not sure what it's made of.

Zirconium silicate (Zircon sand). It has almost triple the atomic weight of regular sand (mostly silicon).

If you have a foundry close then go there and ask for some of their black sand. They will probably let you have a bucket full. Black is the heaviest.
