Going back to the original thread, I'm not sure how traditional reefing and lazy-jacks are related.
Lazy jacks just control the mass of main sail when lowering it. They are not involved with the reefing process.
With your roller reefing boom, (I've never sailed on a boat with this method of reefing - so I'm speculating a bit) I assume you would need to put in reefing cringles and reinforcing patches on the main sail, as well as reefing nettles in the body of the sail. Also, rams
horns at the tack and/or
lines from tack and clew down the boom.
All this is doable of course, just needs a little time and effort and a little forethought to get it right.
For instance, both the
lazy jack lines and the reefing
lines will be on the boom somehow! You will need to prethink this, so they don't interfere with each other.
Have a look at other sailboats to see how they do it. I've got both and it works fine. I suspect the most difficult part is sewing the reefing patches and putting in the cringles.
