Hi TBG, you will most definitely have to replace the sheaves at top of mast. I did a major overhaul of my P-30 last year ( still working on some finishing touches). One thing I did was remove the sheaves and cleaned them up with a wire brush. They were pretty scraped up from the cable. Also, the sheave it self is not designed to run rope. I am replacing my halyard this month, and staying with the rope to wire. Good luck

Hi Stumble. Not familiar with dyneema. Would prefer rope but didn"t think 3/8ths would be smooth thru the sheave. Does it hold up well as far as fraying ? Will have to investigate and see if this is feasible, thanks. This is what I like about this forum...many different perspectives.
