Just thought I'd send a quick reminder about not throwing feints if you can avoid it.
I've just ran 13ltrs of feints (which included 4.5ltrs of BWKO feints) collected over the last year or so, and ended up with just over 3 litres of very, very good neutral. Yes the yield is a low but it's good stuff being thrown out, and if you have the time and inclination you'll be pleased you saved them!
Cheers.!
