My dinghy metal shrouds have worn out and I plan to replace them with Dyneema DM20. To connect the dyneema to the mast I plan to use a t-eye:

No am wondering what is the best way to connect the dyneema to the t-eye. There are two options. Using a cow-hitch like this:

or splicing the t-eye directly into the dyneema eye. 

I am wondering which one is more secure. The first option is easier in practice but I am wondering whether the strength of the dyneema will suffer alot because of the bends.

I’d splice directly to it and not worry about anything shaking loose. Depending on what you’re doing at the bottom it will be just as easy. 
 

Although, what’s wrong with going with wire again?

It depends a bit on the exact relative diameters, but the cowhitch is generally a bit weaker (like 10-15%).  

However, I presume you have sized the stays for creep and they are 'over strength', it which case a small strength loss there is probably moot.

I personally would (and did on my own check stays) do a direct eye splice - but dont stress over it, either one you prefer will do the job.

I just replaced my babystay with dyneema, using the lower fitting that was pictured.  I went with the cow hitch since it seemed to give a bigger radius.  Not sure it makes a difference though, but this was how Selden pictured it.
