That's the unit I have on the 22, and we wasted the sheave bearings. I've been trying to get a replacement sheave, without luck so far. Anyone know of a knowledgable Ronstan dealer? I've got a new Harken equivalent complete unit, but the mounting holes are different, and I'm alway resistant to drilling more holes in the mast.
We also trashed the spin hlyd blk above the hounds, a Harken bullet. We're running a tapered 1/4" Flightline halyard, recommendations for this blk? I'm considering one of Ronstan's wire blks, as only the tapered section runs thru the blk. I've used Harken's wire blks, but there's enough slop between the cheeks and the sheave to allow the line to jump the sheave. The Ronstan seems tighter.
