Hi Robert,
a nice selection of maneuvers. If fuel consumption is such a big issue you might consider replacing the square horizontal eight with, say, two snaps in opposite directions. Back in the 'good old days' I put together a couple of schedules (fortunately I did not have any fuel constraints): a 'calm' weather schedule (lots of verticals) and a 'windy' weather schedule (as many rolling maneuvers as possible). Since fuel is a potential issue, having the spin last only requires enough fuel to get to altitude as you can land dead stick if necessary. Tony is right about the spins - practice!
Good Luck!
