Top bars are tricky. I started with 2 and regretted it almost immediately. If you're looking for some mentorship, I know the guys at beekeepingmadesimple.com offer help and are pretty responsive to their online students. Do you have a specific question we can help with? Do you live in a place with a cold winter? Overwintering a top bar is a little harder but can be done. Let me know if I can help.
