Am I reading into your responses that a 150% makes more sense than a 155%, unless I live in an area with only light winds? Can anyone write knowledgeably about a fully-battened main? Is it substantially more expensive? Does it have a performance advantage?

CDI supplies specific information for your sailmaker to correctly build a sail that will hold a reasonable shape when partially furled. I would go with a 150 if the prevailing winds in your home waters are consistently light (you can't furl a 150 down to a storm jib). The first sail I had built was a 135 made from a heavy Dacron cloth. I frequently encounter wind conditions of 20 knots or more and didn't want to risk blowing out a 150 that I would have made out of a lighter fabric. Next year I may order a 150 and change headsails before leaving the dock as conditions warrant (it's not that difficult to change sails on the CDI).

I find the CDI furler does a good job of reefing. I have foam in the luff on my 150 which helps the sail maintain its shape when reefed. This time of year in San Francisco Bay I use my working jib as there is usually a pretty fair amount of breeze particularly near the Golden Gate in the afternoon.
