Jack,

Thanks for the data point.  I'm glad the compound brakes are working out for
you.  I have had my set of brakes brought up to "Rev. A", so that part is
good to go.  At this point it looks unlikely that I'll be using them before
mid-2004; I just ordered an engine, which is supposed to arrive this
October.  Still lots of work to do!
