Isn't there already a thread or two (or three or ten) devoted to the merits of TWS vs. M1? Maybe you guys can keep this very useful oil analysis thread focused on oil reports and analysis instead of rehashing old debates?
P.S. I'm using TWS and had high aluminum and iron levels (7 and 12 respectively) on my report. Lead was low though. Still not sure if this is something to be concerned with.
