I use Goodridge lines and if they are good enough for Europe on European cars then they will meet my requirements. I have heard every reason for buying them in Australia. Most insulted when a bloke sold me some custom ones here that had GOODRIDGE on the side of the hose. Same thing just more expensive.

Looks like you and I are on about the same path based on this, when are you planning on getting it all finished?
