Brake lines 3 vs 2 lines?
Is there a difference with the 3 line set up versus the 2 line set up for the front brake lines?

Article below is taken from Hel's web site, think it will answer your question. Most people I know recommend the 2 lines and it's what I have always fitted. Install is easier to do etc.
Article: -
Brake Doctor - What's better - three front lines using the oem splitter, 2 full length fronts or 2 fronts with one over the mudguard ?
As we have said above the three systems give the same performance but the three line front has an additional 2 possible leak points in the system, is heavier and harder to bleed than 2 front lines. It is easier to fit though as you follow the oem setup. Another thing to remember is do you race or use the bike on track days ? If so go for the 2 full length front as in the UK one of the ACU rules state that you are not allowed an over the mudguard system unless it is an original system.
Brake Doctor - What is the difference in performance between two full length front lines and an over the mudguard line kit ?
Nothing except for the way the system looks. Both systems operate in exactly the same way and give you the same performance. As the system is a closed hydraulic system without air in it when the fluid moves at one end the same movement takes place at the other end. Because they have different lengths doesn't mean that the system will work slower at one end than the other. Imagine pushing two sticks away from you which are both 6" long - the ends both move at the same time. Now imagine pushing two sticks - one is 6" and the other is 36" - the ends still both move at exactly the same time. So the over the mudguard gives the same performance as the 2 full length - it's just which you prefer.

Interesting article.
What I've always wondered about was the GSXR front brake line configuration, with a single line from the MC to one of the calipers and then a second line arching over the "mudguard" from the first caliper to the other.
One would assume that the same theory would apply. Kinda.
