Don't worry, most everyone here is a simpleton, don't let the big words fool you.

Joe - I think what these guys are saying is that the compression test
will tell me if there's a big hole somewhere, which may be the case. If
it is not the case, then the leak down will tell me where the smaller
hole is/are (to a fairly accurate degree) - so, might as well take the
extra 20min to do a leakdown in case its not a big hole, or its several
smaller holes that make it look like a big hole - 

I think I need to work on my technical terminology a bit eh? I'm just a
simple guy using simple words :)

Vittorio -

It takes just a few seconds to whack yourself in the head with a  
hammer. That doesn't make it worth doing. I totally agree with PJM, he  
hit the nail on the head.
