Exclamation thinking about replacing standing rigging

I am thinking about replacing standing rigging with : "AmSteel-Blue Dyneema SK-78 Single Braid".
Any thoughts?
It has a breaking strength of 2500 lbs more than wire rope which is 2100.
Is this a good or bad idea for a 1974 Cal 21 (trailer boat)?

Any comments appreciated.
Thanks

I am not sure what the advantage would be over the stainless steel wire rigging other than the strength. Do you need the additional strength for your Cal 20? What is the cost vs stainless steel wire rigging?

Cost is higher due to higher terminal cost. But it would be better on a boat that has the mast raised and lowered alot.

Ok, I guess that it will be a good move for your boat. If you are taking yours in and out a lot I can see why you would want to have as lighter rigging. Go for it...

Not just lighter. My issue is I keep bending my turnbuckles raising the mast. The dedign was more for two pleople not one idiot like me who cant wait to get on the water quick enough. Lol

Chafe. Just something to think about.
I love dyneema, and the newer coatings they put on the fibers really help against sunlight damage. I've changed out my lifelines and have been very happy. Saved a bunch of money and installed them myself.

For standing rigging, I'd inspect them heavily at least twice a season. Every 3 months? Specifically where the cap shrouds go through the spreader ends. Also how are your headsails attached? Tuff luff? Hanks? If they're hanks, you may want to switch out to soft shackles (you can make those at home). The 'normal' hanks will chafe through the forestay in a short time under heavy conditions. I wouldn't use dyneema under a tuff luff foil. To hard to inspect on a regular basis.
