Brake Setup Dilemma

OK, peeps. My 88' TurboII is getting a braking make-over. I'm going with 13" rotors all around with Wilwood SLRs all around- just different piston sizes. I've got the option of setting up my braking system one of two ways:

Complete DIY pedal box on slider
1. Floor-mounted: on seat slider system
2. 5.25-1 pedal ratio

Positives
1. Adjustable for other drivers (wife, sister)
2. Can move seat to rear-most position for optimal weight distribution
3. Set-up 90% completed-not installed
4. Cool factor-damn proud of it!

Drawbacks
1. Relatively heavy-5.90 lbs
2. 5.25 pedal ratio (all manual system)
3. Masters to sit at brake caliper height (bleeding issues?)

OR

DIY Brake arm using OEM location

Positives
1. Easier to build and build quickly
2. The ability to increase leverage to 6.0 to 1
3. Master cylinders sit at higher plane for easier bleeding
4. Will only need to utilize two masters cylinders instead of three, thereby freeing up the third master for hand-brake usage
5. Can locate masters in engine compartment increasing safety
6. Lighter weights involved

Drawbacks

1. Cannot easily adjust driver setup for other drivers
2. Must build new master cylinder/firewall bracing for the added PSI needed to operate system.

So, that's what I've come up with so far. Any and all thoughts are welcome.

If you use remote reservoirs, mounted higher, I don't think bleeding would be an issue. I've never seen it be a problem anyways.

If your going to use the Franklin method (positive's against negatives) Having way more positive's, the second choice wins.

LOL! Thanks, Gian! Yes, I would think that the 2nd idea would be best, but what I was hoping for was the wisdom of racers before me (like you!) that may have had the same dilemma and may have come up with other "drawbacks" that I may not have foreseen. I hope that makes sense.
