There are several varieties of “Chain” floggers and just like the difference between suede/leather/rubber each style of chain will feel a bit different. Just like other floggers it is based on the size (width/diameter/thickness) of the chain, the style of chain (beaded vs. weave/link/maille) and number of falls overall weight.

My advice is to practice and see how the falls fly/spread then start very lightly and slowly.
