I would re think the 9 frame deal.
You want 10 frames in the brood chamber at all times.
10 frames until the comb is fully drawn out, in the honey super.
Once the full frame has been drawn out and you x-tract the honey then you can put back as 9 frames.
The bees will draw it father out and you will have a fatter frame of honey, which is easier to uncap.
The 9 fat frames has as much honey as 10 slim ones.
You will get an erratic comb using only 9 frames to begin with.
You may even consider starting with every other frame with foundation to get a more even comb.
What I'd do.
