Knowing nothing about that I would say would shavings. Seems like they'd have a little more give to them and might shift down a little less. Thats just a guess though.

id use leather shavings. i heard it prevents settling at the bottom, which is my biggest problem with owning a heavy bag.

Its only to top the top bit up guys

go with the wood.

Save your money and get a filled bag, or take it to a professional upholsterer to fill......
