Should we use Narrow Money or Broad Money when forecasting inflation?

In a previous thread, KShartle managed to get a discussion locked when he resorted to insults instead of explanations. I simply wanted to know which financial assets should be counted when forecasting future inflation.
Obviously, this is a fundamental question that needs to be answered before any debate on forecasting inflation can even happen.
From what I could gather, it seems KShartle and MDraf believed that only "Narrow Money" (high powered money or base money) should be used to forecast future inflation. After all, Narrow Money is our medium of exchange.
Unfortunately for them, economists who believe they can forecast inflation by looking at the money supply will use Broad Liquidity or MZM (previously M3) or a form of Broad Money when trying to model their forecasts — usually as part of some function that includes velocity, etc. After all, the overwhelming majority of our personal savings (bank accounts, money market funds, and T-Bills) are invested in highly liquid non-cash assets.
So, which is it?
Should we use Narrow Money or Broad Money when attempting to forecast future inflation? And be sure to explain why.
