Front brake lines; use 1-2 splitter or just use 2 lines from M/C to caliper?

I'm getting ready to have some braided stainless lines made up for my '84.  Looking through the related posts here, I heard mention of using two individual lines from the master cylinder down to the calipers instead of the stock system of one line down to a splitter which then feeds both calipers. 
Is this a good idea?  One of the immediate advantages is that I only have to buy two lines instead of three.  There would also seem to be less potential places for leaks or air bubbles to hide out. 
Are there any disadvantages of doing it this way that I'm missing?  What do you guys think?

Yes.....go with 2 lines from the m/c....... use the double banjo bolt from the splitter.

You are correct in your air bubble assessment.

+1 on 2 lines.
Cheaper, cleaner, less problems bleeding, etc.
Have you already deleted your AD units?

Cheers,

Only disadvantages that I can think of would be the added bulk at the master cylinder and having to route two lines farther instead of just one.

I'd go with two lines vs three in a heartbeat.

 I have been running one line from the master to the right caliper, then a line from the right caliper to the left caliper , for a few years. This uses the least length of hose. Triumph and Suzuki use this setup.

Sounds good, guys.  Thanks.  I'll be taking some measurement and ordering up some lines.  I think that I'll go with the 2 lines from the M/C method.
I plan on disconnecting the A/D units when I swap the lines.  I'll be leaving them on the forks and putting a stainless button-head allen screw in the hydraulic ports.

I did the same thing, about 10 years ago..... works great!

Get a pesky air bubble at the top of that loop, and you *will* wish you had 2 lines running uphill to the master cylinder....DAMHIK

Hmm...  That's a good point.  I was kind of starting to like the caliper-caliper idea, too.

 I have this hose layout on 4 bikes and I've never had a problem with an air bubble at the top of the loop! I always use fresh Dot 4 , and don't use any fancy bleeding tools. I know some folks have problems getting the air out of their brake systems, but not me.

Not a problem, Mity-vac and removing the caliper from the fork leg fix that.....Haven't had an issue in over 10 years.
