Crankpin, as you practice your sequence more and more you will get used to flying one maneuver to set up the next and your caller will be there more to remind you in case brain fade sets in. Having said that it's really nice if you can have a caller who practices with you a lot. That way he or she will know the maneuvers you're having trouble with (that particular week, they change, lol) and may remind you, for example, to push the stall turn all the way to the edge of the box or start something earlier or later. A good caller can calm you down when you screw up badly with a couple of encouraging words and help you get back on track.

When I'm calling for someone I don't know well I always ask if they want reminders and suggestions or just want the maneuvers announced. If you don't know your caller it wouldn't hurt to let him know what you like.
