I agree with Tony, I plan on flying both this year simply because there are only 2 IMAC contests a year here in AZ. But ouch, back-to-back weekends this April (SCAT/IMAC). Practicing weekends only for both sequences won't be too bad for us sportman classes but just think of the advanced and unlimitted pilots with complex sequences. This could almost kill the already dwindling participation in the Spring IMAC in Tucson the following weekend. I hope communication between the two groups is better next year. I love aerobatics, no matter what the "organization" is called.
