I'm with Jayson on this one (Jayson winces in pain :x :P )
I use to just give my lines to Bayflite (remember) and put Qline on.

Firewire breaks, other stuff is tougher.
I use to use Q line for everything. Found something even stronger (Ozone lines -- 800 pounds baby!!)
Flexi has some awful strong stuff too.
Plus, is FW still all white?
