FWIW, when my car was restored I paid no attention to parts manufacturer and just bought what I could from Miller's. When I recently checked the brake hoses (they are now 15 years old) they looked brand new. However, there's no getting around the 15 year old thing, and rubber IS rubber--so after 15 years of flawless performance these hoses--which are FAG if anyone is interested--are going to be retired this summer. I just purchased a full set of four from Dave Gallon. They are all new ATE. Since the braking system (calipers and booster) are ATE, I think ATE hoses should probably be OK. The total cost for all four new ATE hoses was about $50.
Yes, stainless braided brake hoses look cool. On my car, you'd have to jack up a corner, and take the wheel off--OR lock the steering wheel in one direction and peer in for any admiration; flex lines are not that visible. The other argument FOR SS lines is that they tend to expand less thus reducing any soft pedal...
