Miles sailed? We sail about 50 hours a month in the Caribbean trades and also do passages . Our mainsail has 6 full length battens, and C size Batt Cars. I’m afraid the luff tape would have to be replaced quite frequently with in boom furling. Sun, salt and big wind/seas are very tough on gear. We’re rarely in a marina so the opportunity to flush gear routinely with fresh water is miss.I had a Leisurefurl on a 38 foot boat. I liked it a bunch, but I tore through a luff tape almost every year. I sold the boat 6 years ago. The new owner hasn't torn a tape yet.
