I bounced around on that question for awhile for my 87 SHP and just went with a Hitec 7954. It's stupid overkill, but I wanted something reasonably fast and all of the cheaper HV servos were too slow. Also in a pinch I could swap it out for one of my 7955's since the specs are the same, just not titanium gears.

I would be really hesitant about using a bunch of diodes to drop the voltage down for a regular servo. They're usually about a 0.7V drop under load (less with no-load), so you would probably need 3 of them to get a fully charged 2s LiPo below 6V. You can get a fairly inexpensive and small inline voltage regulator since it would only be operating a single servo.
