Mainsail reefing dilemma
A couple of points came to mind while reading this.
1. If your boat is designed to have main reduced you are better off reefing main than furling a jib.
2. Jiffy reefing would be easy and fairly cheap to implement. Ensure that a sailmaker puts in the grommets so there is adequate support to the surrounding sail.
3. My experiences with a loft are that they charge by the hour and the work you need done requires very little time. It will not cost very much to install two gromets in the main! The roller furling of Jib will certainly cost far more than any Jiffy reefing modification.
My 2 cents. Hope you have a great sailing season!
