One long ass wire about 80 feet long 15 or 20 feet in the air sloping down to the ground feeding into one of these: http://www.mfjenterprises.com/products.php?prodid=MFJ-941E
Yeck. Random wire will need constant adjustment with the tuner (which is not weatherproof and must be in the shack) and then you'll need the proper RF counterpoise wire. I think you'll have RFI issues, etc. What happened to the inverted Vee dipole? That'd be your best bet.
And 15-20 feet up is pretty low. You'll only hear the really loud stations and hope they have good ears to hear your puny signals.
MAN! I wish 6M
Even with sunspots 6M is overrated; don't get too excited about this band. It definitely will not be like 10M will be.
and 10M where open at the moment.
You gotta wait. 40/30/20/17 are the money bands and that's where you should concentrate your efforts. A nice multi-band vertical would be what I'd do.
