I am going to use Buddipole for the NVIS antenna. Did you go good results for similar operation in the past?
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.
