Bushveld,
I am not using Tru-oil, just opening up a debate about the variety available.
Mike Smart is a good friend of mine and I have used Trade Secrets since Mike started, incidentally Mike used to work with Clive Lemon of CCL and I prefer Mike's brew.
Mike used to work with my apprenticemaster Bert Williams who was Foreman at W.C.Scott , so I guess all these concoctions have a little customisation going on.
