I don't make much now and don't make stuff to sell on here anymore anyway, but unless I'm just messing about or showing someone how to go on, I use the best quality hide I can find.
I've never used cheap or poor quality hide for
anything intended for sale.
I've always found that good quality hide is easier to work with and often more forgiving than the cheap stuff that may not have uniform thickness, has soft spots or hard spots,scars, blemishes,is too soft or too hard overall etc etc.
The thing to do is to use cheap stuff for your prototypes,experiments and in my case, stuff for my own use!:bluThinki and then use decent stuff for your "real" items.
Using decent materials means that the only things that can lead to "comebacks" are poor workmanship on your part or misuse by the end user.
My experience of buffalo hide, is that it tends towards being quite supple, very durable and strong. Tooling wise it doesn't work like normal veg tanned cow hide and it always has a more natural, wrinkly look to it.
