Roger is great with the details - try some of his suggestions.
"Rigging to specifications" may not result in a perfectly rigged sail. New sails normally can't be rigged to the recommended downhaul until they "break in" and stretch some. Old sails may need to be over downhauled as they wear and streatch.
If you have to under downhaul to gain power in the sail, resulting in a sticky cam, then the solution is to either rig a bigger sail or get used to punching / kicking the cam. Try the Mclube on the sticky cam and you may be able to get by with under downhauling. Back off on the batten tension too unless you get too many wrinkles.
