In other words, don't stack the deck against yourself so heavily.

Reminds me of CQ article.  The author took a 1 w rig, buddipole and a
beach chair to the shore.  After two days he made no contacts.  He said
he had fun.  So maybe fun isn't all about making a ton of contacts--
perhaps the scenery at the beach was enough.

If contacts are what your after, Frank's points are all well taken.  In
these days of low sunspots bring the highest power/power source you can
lug to the game. It's the opposite of the usual expression.  They have
to hear you to work them.
