Second thread with same question?
If managing the main (all 222 sq ft of it) is a concern for you, you might consider a smaller boat. There are many things on a C30 that require much more effort than the little main on a C30.There is a reason that mainsail handling systems are generally designed for boats bigger than a C30. Little boats don't need such systems.That said, (as I said before) the Harken system is very good.The stack pack works for some people in some climates. The stack pack has a zipper that runs the full length of the boom, the zipper is hard to get to on some boats. The zipper is also not water proof. In rainy climates, mildew on damp sails inside stack packs has given them a bad name.No combination of sliders, lazy jacks, or whatever is going to be automatic. You still must leave the cockpit to deal with the main.You might consider a furling boom. Forespar and Seldon both offer furling boom conversions that will work on your 30.
