    you could swap the winch wire for dyneema = no more twist
    I have just stepped my mizzen (I don't know if you remember but we have *very* similar boats and are on *very* similar journeys) yesterday
    I stretched one cap on a massive yard frame (and burst a 2 ton ratchet strap when I pulled sideways on the tensioned line)
    The other lines I just installed and then have been stretching in place by over-tesioning and then 'hanging' off it. This method causes sore hands but achieves the same thing
    I stepped it using a lashing between the turnbuckle and eye, tensioned by hand with a marlinspike hitch on the lashing, then would up the tension on the turnbuckle and pulled it around, backed off the turnbuckle and repeat a couple of times then replaced the lashing with a rigging link. I've also been getting about 100-110mm 'stretch' but I am using Liros DM20
    My mizzen rigging is slightly different - I have 4 lowers, but then my spreaders are swept well forward and I have 2 removable backstay (that I think I am going to rig like running backs with a cascade)

      Dyneema in the winch would be a really sensible upgrade!

      Our turnbuckles were a very mixed bag so the cost of new chainplate bolts and turnbuckles was a key factor in our choices.
      Having the combination of lashings for coarse adjustments and turnbuckles for fine adjustment is a good one.

      DM20 is supposed to be one of the best options.

      @@SustainableSailing as the loads are relatively low you could use 3-4mm and then when you are finished recycle it, making soft shackles

      @@SustainableSailing I'm not sure I'd use it again - I used 8mm for the mizzen just because it worked out sensible to buy a roll (mizzen caps and Main lowers were the only ones *needing* 8mm) but having the larger diameter for the mizen lowers certainty makes moving around nicer than grabbing thin lines.
      Maybe I will change my mind over time as supposedly DM20 is zero creep.

    Also you have never explained the reasoning behind switching to that black rod from fr4 could you please do it in your next video maybe?

      We had a lot of help in the comments. Basically the conclusion was that Acetal is better suited to the tang use and it's more machinable so we were able to create a better shape.
