Ryan, for me anyhow I use Hide glue because it is reversible, without totally F-ing up what work you already have done.
At the end of the day it's pretty cheap, does require some maintenance if you are using a pot, which I like. But it will be useable for a longer time, and when it is right your open time is pretty good.
I understand the PVA's and Epoxies all have a ton of science in them, while Hide has only had that one advance. However since back in the 1700's when some Farmer who didn't know how to spell or write was taking dead animals/fish and turning them into adhesive, well there has been a ton of science added to the manufactured Hide product we have today. So it isn't "that" hide glue we are talking about, it's a perfectly made product from the lac bugs, but the processing it has had done to it, well there is a lot written about it. Plus "that" hide glue had a really good lifespan, and a lot of stuff made by the better full time shops has aged very well.
I do advocate for the use of GERMAN made, machine made only. I too have some wonderment about the Indian made stuff that again, some dood who can't read or write, making my glue products. I guess that has me coming down hard on illiterate folks, just saying they aren't scientists. Doods in Germany are.
