Timing for a meet.

My masters team(Chattanooga River Rats) is looking to host a scy meet this spring. We are trying to decide when is the better time to host the event. We are deciding between middle-to-late March or early April. There are some that think a mid-late March would be good time. This would be before the entry deadline for nationals, so someone could attempt to make a nqt. Others think that a tune-up meet in April would be better, since people can swim 3 events without nqt's. If you were looking for a spring scy meet, what would be your idea time?
