We have a self tacking battened jib on a straight track on our ARC22, so the jib is always up when the spin is out. When sailing recreationally we just release the jib sheet, and it floats in the slot quite docilely. If we're looking for max power, we can apply a small amount of sheet to get the jib telltales flowing appropriately. Doesn't seem to force us particularly high, although the chute is quite flat and doesn't run real deep.
