I change to the thickest rope that will pass through blocks in winter.

I switch between 7mm and 9mm polylite on the Europe depending on wind strength.  It is less tangly than others I've tried and relatively light.  I probably won't replace the 9mm as 7mm seems fine most of the time.  The sheet load is actually quite high on the Europe as you are controlling leech tension with mainsheet (kicker isn't used upwind).  I'll try 7mm on my N12 too as what I have on that is way too heavy.  It makes a mockery of the carbon boom it's hanging off!

One thing to watch is wear on the outer cover which is the load bearing part.  When it fails, it really fails, so the note Rooster dispatches with it recommending that you replace it annually isn't just a money creation effort!

End for end it every now and then, the wear will be at the ratchet upwind position.

Yes, I did that and had two fraying areas, one of which eventually went ... as I sheeted in on the gun of the final race of the nationals with it all to play for.  I have learned my lesson  Smile

The only place I've ever broken a dinghy mainsheet was also at a Nationals. Spooky!

I suspect some ratchet blocks are better than others for sheet wear?
I have a big Ronstan auto ratchet on the 400, and the sheet is lasting well. I tend to use more sheet tension and less kicker than most people, so it gets fairly well exercised.
The question is, are particular blocks good with particular rope combinations?

Is Dyneema worth the extra over pre-streched Polyester or Polypropylene? i.e. it the limited stretch an advantage (I'm asking because I have just replaced the 4mm dyneema main halliard on my Spice with 5mm Excel Racing and it has about 150mm of stretch in it over the 6 metres or so between the head and the cleat when the sail is up the mast).

I like a mainsheet to have a touch of "give", whereas a halyard needs to have as little as possible.
