Even going in fully expecting a
high roll rate, I could barely slow it down with full deflection.

Wouldn't a good technique be to pull "up" once you are near 90 degrees?
It would pull you out of it. Or would you end up stalling?


Even knowing it was coming, you're out the side of it and in an unusual
attitude before you can even think about what to do. The Lakes could go
360deg in less than 2 seconds and full aileron agains the rotation barely
slowed it down, so trying to fly out of a violent "fresh" one is moot.
If you were to take an example in which a typical lighplane, on approach,
were to encounter strong wake at, say a bit above approach speed, I believe
it' be on it's side, if notalmost compltely inverted, and ejected out the
side of the vortice with a pronounced nose down attitude before you knew
it. Basically what you have here is a well advanced botched roll. Any
aerobatic experience and you're back straight and level in a flash, but for
someone who hasn't got that experience is probably going to lose a great
deal of altitude and/or gain a great deal of speed recovering.

BTW, even an airplane the same size as your own will give you a bit of a
bouncing around if you're close enough. Something twice your weight can
easily cause you to lose control, at least momentarily. If a 172 were to be
following a big-ish light twin with less than a minute's seperation, and
the 172 was slow, you could get an unexpected ride for a second or two.
The classic encounter on approach is when both aircraft are following the
same glidepath and there's a ligth tailwind. The tailwind will bring the
preceding aircraft's wake up into the glidepath, especially if there's a
slight x-wind component.
