I'm sure I can arrange for Friday practice, but not everyone can take that Friday off to be there. Those people may rather spend the incremental costs of an additional trip (it also spreads out the costs of additional tires and entry fees).

There are pros and cons to each option, and everyone gets a vote.

And please remember that this "vote" is quite informal and is for informational purposes only. It does not bind me to any of the options, I just want some feedback.
