Heres about the best thread Ive seen on blending ,the guy has been in it for around 19 years now and runs some of his farm equipment on his special blend ,the key he says is the prep for the wvo ,he will not comprimise for time saved on his proven method of filtering and setteling ,sounds like his got it down to a science. His site name is JEFF47 AND THE THREAD IS ON FRYBRID .COM ,A 2 tank kit company .http://www.frybrid.com/forum/showthread.php?t=3282
He gives you his formula ,tested filtering techniques and general knowledge of his blending methods ,a good read.
