I just have the one maul. Also only have one nylon hammer. Mine probably weighs 24 oz. (1.5#). I use it for everything, just adjust the amount of force depending on the size of stamp. Or adjust the number of whacks. When doing basket weave stamp, I normally whack it once or twice. for my maker's mark (1" x 1") I whack it 2-3 times really hard. Anything larger than that, I put in the arbor press.
Make sure to send pics when done. I would enjoy seeing your creation.
