<<Say for example you take your a/c [ a Decathlon or whatever] and put
it into a spin to the right..  Obviously you'd need left rudder to un-yaw
the a/c so now both wings are flying.. but.... [for example] your in a 60deg
right bank, 60 deg nose down... do you at this point use rudder or rudder
and ailerons to first roll the a/c level and then pull from the ensueing
dive. That was what I was meaning when i stated that I was trained to use
both the rudder and ailerons.>>

One can use both rudder and aileron to recover from spins.  In fact, in a
fuselage loaded aircraft, aileron is the _primary_ spin recovery.  BUT--you
use aileron in the direction of the spin, which is the exact opposite of
your natural reaction.  In the case you mentioned, left rudder and right
aileron.  The NASA standard recovery (if I remember correctly--get it mixed
up with the NASA modified) is to use rudder against and aileron with.  I've
spun a lot of different airplanes, from gliders to A-4s, T-33s, T-2Cs,
T-28s, T-37s, A-37s, and light airplanes; and departed a lot more, A-7s,
T-38, Boeing 737 (unintentional), and F-4; so I've spent a considerable
amount of time out-of-control.  I really enjoy it.  (Some people say I'm
usually out of control!)

I've followed the thread with interest and have to add my two cents.  To
truly understand an airplane, I believe one has to fly it to it's limits,
which includes uncontrolled flight.  Only in this way can a person fly an
airplane precisely and confidently.  I'm on my third flight in my finally
completed L320 and fully intend to explore the complete capabilities of my
airplane during the 40 hour flight test--including out-of-control as well as
determining the maximum airspeed.

I'll let the List know how it goes....

Best,
