Hi Kevin. First off, know that many folks that try different films ask this question on every roll! (I do.)

Regarding your spot meter: I recommend carrying a 15% gray card to read off, unless you plan on spotting the whole scene to see how many stops you need.

Regarding your development: Do whatever necessary to be consistent with your agitation schedule and temperature. If you vary either of these, you can never really know the reason for your results, good or bad.

Recommended times and dilutions are starting points. It's boring as hell, but the best thing I've found is to put my grey card in a scene and shoot a roll and see what happens. If you plan on spending time with the PanF+, I really think this a good idea.
