I'm looking forward to the C18 and D20 as well.
Will try the short delay ones of each in my Mars Landers then get a bulk-pak of Ds.
Might even get out one of my old 1284 Space Shuttles to try the Ds too.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
