Question Power vs manual disc

So my '66 has power disc front/rear conversion from Master Power Brakes. 9" booster with 1 1/8" master, single piston calipers, EBC green pads all around. Brakes work ok, but its almost impossible to get a wheel lock if needed (front or rear). With marginal vac at 13-14" you have a "one pump" hit on the booster. I've completely flushed, bled and tested pressures (right at 950-1000 psi) and pretty much eliminated any of the components including proportional valve. I don't want to run a vac pump or canister, not in the program. The only thing I still need to do is replace the flexible brake lines that are now 15 years old since replaced.

How many have converted back to a properly setup manual system? How do you like it? I'm thinking lose the booster, change the master & go braided lines all around. This would clean up the firewall not to mention easier valve cover access.
