This article is from 2012 and the off-shore rules have changed for racing boats. There is a note at the bottom regarding inshore racing and cats that needs confirmation.
I used CS Johnson fittings for the upper line when they were on sale at Defender. A number of suppliers carry the CS Johnson fixtures:

These fittings aren't required and I didn't use them on the lower line preferring to experiment with lashings. The lashings worked so well I sort of wish I hadn't spent on special fittings, but fittings work great, especially around the gates. I lashed through the tiny welded D's and around the tubing on the pushpit and pulpit. The Johnson fittings terminated at the tiny welded D's.
Here is a terrific resource and very informative including photos from US Sailing in 2014 (again note the change from current rules).

One very worthy side note is to "sew" Bremmel and deep bury splices. Sewing the splice doesn't add to the structural integrity, but does keep twitchy fingers from "worrying" the splice loose.
Believe any instructions that say you want to taper and "bury" 72 times the diameter of the line. A 6 mm bury would be roughly 17". The bury is a bit like those rattan finger puzzles that tighten as you try to pull you fingers out.

The eyes of the splices were supported by thimbles. This increases strength by increasing the diameter of the loop in the eye.

Worthy of note is to paint lashings with vinyl tool coating or acrylic paint, not only does it prevent worrying, but it looks really nautical and is quite satisfying.
Lastly, and perhaps most importantly is to not,
do not, tie knots in Dyneema. Knots weaken line significantly (as much as 50%) as opposed to lashings with multiple turns, and the slickness of the material will eventually untie under load.
I'm not racing, like the clean look, and low maintenance, and will replace the line about every 5 years or so, give or take. No regrets what so ever for going this route.
Cheers,
