Goodridge brakelines.

[Ivan141]

The handbrake mechanism is operated with a metal cable, so what kind of brakelines you use should not make any difference unless you have some kind of hydraulic handbrake mechanism (custom built).
Consider this: maybe the fluid-change and proper bleeding caused 90% of the effects you are describing, cause I havent noticed such dramatic improvements from fitting goodridge lines at all.

I dont know why your handbrake is working better though, I believe it mechanically pushes the piston out a little, so it should work no better or worse than it did before, unless you either rebuilt the caliper or fitted new discs/pads at the same time.
