RE: caller??????
Unfortunately in IMAC, a caller is a MAJOR part of your sequence in the unknowns. You really need someone you can trust for those. You essentially need to have 100% confidence in what they say and just fly the maneuvers. Trying to memorize unknowns the night before is virtually impossible and also takes away brain power to fly the sequence. The knowns arent bad as you will probably have them memorized, but find someone you trust to help with unknowns. Fortunately at most contests you will see a lot of the same people and you can develop a relationship with someone for the unknowns, even if you don't fly with them regularly. Preferably someone above the class you are flying as they will be able to provide insight that someone on your level may not be able to.
Get to a judging seminar and meet some people there. You may surprised and learn there is someone reasonably close that also flies IMAC.
Most of all,
HAVE FUN!!
