Anyone have suggestions on replacing battens?

I have Bluestreak battens and have 2 that have splintered.

My question(s) are:

* Should I replace ALL battens or just the two?
* Do I go back to the sail manufacturer (Red Head) to get the right draft cut into the battens?
* Buy them directly from Permex Products or a distributor?
* Perhaps there is a different batten manufacturer that others would recommend?

What about batten strength for cat vs sloop?

I think I read in an "ancient" post about putting x-stiff battens in the top two batten pockets for cat rigged sailing.

Hi All

I don't remember who told me this or maybe I read it somewhere, but if your replacing more than one batten, do them all, and not to put used battens in a new sail. New Sail=New Battens.

Sounds a bit suss to me. If an old batten is the same stiffness as a new batten, they are essentially the same.

Yes but a new batten would be stiffer than the others, because it hasn't been curved 500 times like the rest of them, I think thats where the comment is coming from.

I'm going to do an experiment. Measure the battens now (fairly new) then measure them in a year or so.

I expect that cheaper standard polyester glass battens like mine will lose stiffness over time, while more expensive carbon epoxy foam sandwich battens will hold their stiffness longer.
