I've also thought about taking old lines to a local hose shop and see if they can make them.

Believe me, even new rubber lines give noticeably. There are reasons why most new bikes don't use them anymore.

I don't think clamping rubber brake lines is a good idea. I wonder if that was the start of some of the trouble I have been seeing with them?

That's what I was thinking...smashing the line flat enough to stop fluid transfer might result in the inner liner detaching from the outer. I bet the fluid gets black in a hurry after doing that.

Do you have any proof of hose damage from clamping? In my job as a vehicle inspector I look closely at maybe 200 brake hoses a week - sure I fail quite a few, but seldom see that sort of damage. Of course that's what the safety inspection is for, to keep unsafe brake systems off our roads.

Went for a ride this morning and my brakes have firmed up nicely. I like a bit of flex in my lever - it gives feel to the brakes, and that's why rubber hoses are fitted to motor vehicles, rock hard levers and pedals give little feel. In the days of rod operated rear brakes we used to bend the rod of an over sensitive brake to give it more feel.

Expanding brake line equals less feel, not more. Other than that, you are talking about the amount of hydraulic leverage. That's adjusted through varying the hydraulic leverage, not ballooning brake lines. At least that is the smart way to deal with it while keeping better feel and control at the lever regardless. .

I've done that as well. My Airhead has lines made by a local hydraulic line shop. I just called the ones in the yellow pages and the 2nd or 3rd one said they'd give it a go. I can 1-2 finger the front brake. However, since finding the Earl's stuff, now I'd just figure out the thread pitch and diameter and make my own.
