I have used the equal parts of BLO/POLY/MS and the TUNG OIL/MS/POLY mixes. I have also used BLO/MS 50/50. I do not see a lot of difference in the first two except the price. If doing the Tung Oil mix you are suppose to use pure Tung Oil which is pricey. The Tung Oil you buy at Lowes, Home Depot, ACE, etc is a mixture of Tung Oil, MS, Poly and other "stuff". You can get pure Tung OIl at Woodcraft, Klingspor, and other such places.
BLO/MS works fine for projects that do not get handled a lot. It does not create a hard protective finish. You need varnish or poly for that.
