I used to have a Harken Mark III Roller furling on our last sailboat, on S 2 & it was an absolute piece of crap. It would get halyard wrap & jamb up all the time no matter how we rigged it.
Profurl is a much more robust furler that has a patented halyard wrap preventer built into the head swivel. But I have a Hood furler currently that got damaged last year. The drum plate assembly broke & I though it was done for. But I had a local metal-smithing shop make up new drum plates for me out of 316 s. s. to replace the UV damaged & brittle plastic drum plates that cracked & the furler is like new now.
I always try to fix what I have first before replacing, because at least I know it fits & worked at some point, & its always a challenge to retrofit something new.
