opinions on brake lines, steel braided teflon; stock rubber; 17-19-23mm MCs Options

[dlestep]

...I guess I'll start off with my thinking...
My 73 started with a 17mm MC with stock brake lines. I was experiencing spongy
brakes. After replacing all the lines and rebuilding the stock calipers and replacing
all of the fluid and a proper bleeding. They felt inadequate during a spirited ride
through the Cascades, when I lived there.
I replaced the stock lines with steel braided teflon and changed the 17mm MC
with a 19mm MC. The brakes improved, but the feel at the pedal was more
compression was required (travel).
I have read, more times than not, that the steel braided lines are breaking at the
crimps and leaking causing brake failure. I ran them on my 73 with no problems
from 1990 to 1997 until I scrapped it. I have been thinking of running stock lines.
Have never heard nor read a problem with them...

I am considering a 23mm MC, but I have two questions.
Is there a length difference in the housing (mounting flange to body fwd end)?
With the increase in volume, will the pedal travel increase over the 19mm MC?

With the 19mm MC, when I entered a fast corner, I was able to simply roll my
ankle over and blip the throttle as I down shifted while under breaking.
The pedal travel would allow the brake pedal to be parallel (coplanar) with
the throttle, at that position.
When driving the 72 911, (with a 19mm MC), the brake travel under braking was
less and the brake pedal position was above the throttle, forcing me to
heel-toe, rather than the opposite as in the 73 914. Granted the 911 had M
calipers, while the 73 914 had stock calipers.
Now my 74 914 has Brembo AMs on the front and stock rears.
I was thinking that the 23mm would be better suited to the Brembo AMs, or am
I incorrect in my thinking....
...all inputs are appreciated,
