I did my first pattern welded billt back in 1983 with Jim Crowel as my instructor---he's taught at the ABS school later on IIRC; been welding ever since.
I generally use 20 mule team right as it comes out of the box too; but recently as I have switched away from the great coal I was using in OH I've added boric acid to my flux as well, (Roach Prufe is 98% boric acid and you can buy a pound of it for about the same cost as an ounce of boric acid at the pharmacy...
