With about 4k hours, multil-engine, land, instruments, I downsized from a C 340 Ram to a sweet V35G, circa 1956, with a throw-over control. Since that equipment change, all of my flight reviews have been in rented, fixed-gear Cessnas. You're right, the regs seem to encourage, (for saftey's sake)a flight review, including emergency procedures... (like cranking down the gear, emergency descents, partial panels, etc)....but discourage that training in the specific aircraft that one flies exclusively...... except of course, for that one hour every two years.
