You have many choices, but consider if you only want roller furling vs. reefing, first.
Once you've decided that, then your choices are basically robust systems that have been proven to work, or wimpy others.
If reefing, then choices include ProFurl with its built-in "wrapstop" above the top swivel, or other manufacturers which require a halyard restrainer.
Harken as John said, or ProFurl are excellent.
CDI and Furlex may be less robust.
When you ask a question like this, most folks will recommend what they have, which is logical but not necessarily helpful. I have a ProFurl, been doing great for almost 20 years. John has a Harken. I've seen his, he's seen mine.


OTOH, if you have done your own research, a more realistic question would be: "For those of you with XYZ roller reefing, have you found any deficiencies?" Specificity helps here. Otherwise, your question is like asking your mother: "What girl should I marry?"
Happy New Year.
