That's one ringer. A Buddipole for 80 or 40M will require lots of 
inductive loading, so it will be VERY inefficient. Also, with NVIS, 
ground conductivity matters -- you need good ground conductivity to get 
good NVIS.

It's worth studying the sections of the ARRL Antenna Book on the topic 
of propagation, and how the state of ionization by the sun affects 
whether you have a chance at NVIS. When you're using QRP, you have at 
least one hand tied behind your back. Don't let a poor antenna choice 
tie the other one.
