When I changed brake lines I went first for HEL lines. they didn't reply to an email.. nor did they answer the phone. I needed to speak to them as the online shop didn't allow for what I needed: the upper line 35mm longer than 'stock'.
So.. rather than wait for an email reply (which never came) I went for Goodridge with S/S fittings.. at the time the price difference was 90p for a full Kit - front and rear.
And I was pleased that they didn't charge extra for my bespoke requirements.
At that time.. and probably the same applies today, HEL were supplied with stainless fittings as standard. Goodridge you have to specify them. But as I say the price difference was pennies.
