I recently bought an Australian lash made out of kangaroo leather.
It does not require oiling - which is very nice if a person is at all concerned about a bit of oil on his/her breeches, or just likes less maintenance.
It comes with an extra bit of thin leather that connects from the lash to the popper. This extra bit of length has proven invaluable in reaching a naughty hound - but it is not thick enough that I can tell I’m holding it. It’s very nice.
I didn’t care for it at first - then I realized it’s not the lash that is bothering me. It’s the kennel crop. It’s unbalanced - too heavy and long. It fatigues my hand and arm. So I’ll echo what other, more experienced people have written about the crop itself - find the right one. I prefer a longer lash even for whipping in on foot - but this is a matter of personal preference, I think. If I was on a horse I’d definitely go with a long lash, and if I was at all concerned about having to hold it and the reins coiled - I’d consider the kangaroo leather. The lash is thinner than the traditional lash. (and there is the less maintenance factor which may or may not be important to you)
I’ll second what Beverley wrote about excessive whip cracking. It is a tool to be used lightly - because when you need to stop a riot or something equally horrible - you need those hounds to STOP. If they’ve tuned out the annoying whip cracker you may end up with a serious problems on your hands. When you crack it - is should make those hounds believe that the clouds just parted and God Himself spoke to them and said - no no bad dog.
You also do not want to frighten young entry, especially if you’ve got a hound that needs to develop confidence.
That is just my personal opinion and others may differ.
Good luck!
