Dowty washers or copper for brakes?

Doing a bit of reading of old posts about brake lines and came across this

having just bought some Wezmoto lines with supplied washers, and given I scare easy, would you use these ones with the rubber insert (they're not expensive either) or stick with the copper supplied? Anyone had problems with standard copper ones?

I have only ever used copper washers mate and never had any issues. What are the problems that the rubber lined ones are meant to solve?

this is what I read Kev

Dowty washers are far better as they dont squash down like copper washers. Having said that, the last time I did the brakes on the blade I had to use them as I had run out of Dowtys. The copper washers I had were very soft, and although they sealed OK, it felt like I was about to strip the threads in the caliper as the banjo wouldn't torque up (due to the copper squashing)

You can't re-anneal and re-use Dowty washers.

Plain works for me; never had one leak.
