Thanks for all the advice. I decided to go with the Dazzo pickups. I'm having a luthier who is well versed in installing them as he is a authorized dealer. I think paying the extra for a qualified luthier install is a no brainer.
I will use an external preamp. I think they may be more preamps than pickups to choose from.
It was an interesting selection to make. I think the sound hole pickup was number three and a microphone was number 2 on my list.
They all have their pros and cons.
Again, thanks for your advice and onward to choosing a preamp.
