Whisker Pole vs Cruising Spinnaker
Be sure to get a snuffer. I have used ATN''s with joy, and others without. Snuff then jibe, is reliably no sweat.
If you go with the pole and symetrical you will go faster downwind (but use it much less often). Get a very stout pole, the wind comes up fast in your Chesapeake squalls. I found on my 37, short handed, the symetrical was good for a reach/run, but I would essentially never jibe it short handed (and I was young then).
