First of all SWIMs bark is Acacia and very fatty, so I need the acid step to defat. Second, it is Acacia bark, the quicktek was designed for MHRB, what if there is some major difference in the barks and the quicktek doesn't work and I lose a kg of bark? And third, I don't know if tis is true, but I read letting it sit in lye for a few days means you get alot of extra lye in your final product. SWIM could always try the quicktek on a small amount of bark, but why? The A/B extraction works perfectly for him and he can do it all in a day anyway. If someone else has had any good experience with Acacia bark in the quicktek, I may consider it, but otherwise he'll stick to the traditional tek for the moment.
