The cupro-nidkel alloy was chosen for brake lines due to it's 
resistance to fatigue, unlike pure copper, so that's a point in its 
favor. The downside to this is the fact that the rubber hose almost 
always fails at the connections, where it is slightly stretched. With 
your metal tubing sections, you have a lot more of those connections.

I was thinking that OT would react about the same as WT, but if the 
MS works well with the faster warmup time of the HT and doesn't mind 
the higher end temp, then getting out of the warmup mode quickly is 
certainly a good thing. If that's correct, I wonder why MS didn't 
suggest HT as a first choice.

Yeah, that would be hard.

That sounds like a much simpler approach.
