Do you crab or forward slip in X wind landings

Well, since you asked... Consider landing diagonally or even
perpendicular (in the extreme) to the runway. Let field and weather
conditions help with the decision. Just don't be hobbled by what you
learned in training since that was conducted during favorable weather.
If you're going to fly in weather that wouldn't be allowed for a solo
student, be prepared to do whatever it takes to land safely.

And have fun!

You're right, 'released rudder' doesn't make sense, I meant released the
extreme crab angle returning to straight ahead alignment just before
flairing. The yaw string never was straight during my 300 yard crabbing
final approach. It was extremely windy with the wind 90 degrees across
final approach. I was flying straight, not turning, wings level. I did
get into full right rudder after touch down too, after being prompted 2
quick times by some mystery quest over the radio!

Dan M said not to worry about coordination in this configuration as long
as you keep plenty of air speed, which was my though during this 60
second thrill ride as well.

Thanks for the input. Any additional comments concerning lack of
coordination while on final due to big cross wind landing are welcomed.

a real life experience that happened to me... I still wonder if I did
the right thing 3 years ago. Could someone in the know talk about the
lack of any coordination in these situations?

After returning to the field at 3500' agl, the wind had turned on
final, 90 degrees to the left across the only possible place to land,
on a plowed dirt strip. AWOS had the wind solid at 20 gusting to 28.
I
lingered as long as I could but the massive cell to the east was not
moving or letting up. Nothing but rough desert landscape everywhere
and
altitude winding down.

Field partially disappearing in dust at 800 ft. I set speed at 70 kts,

turned base into the wind, then final and into a deep forward slip,
windward wing down, way down, but not quite holding my target from
drifting away from me to windward. The yaw string was aligned nearly
70
degrees across the canopy which Really got me alarmed. I was calm,
pretty smooth and super focused. Out of the slip and into a huge
crap,
no problem. Yaw string was now about 30-40 degrees out with my wings
level crab at maybe 30 degrees to the left. Had control of my target
now with partial spoilers. Field length maybe 500 yards long or so.
I
went to the deck and released rudder and flared, lowered my left wing
tip a bit I think. Did a wheel landing at maybe 40, full spoilers and
into breaks as the field seemed to be getting short. Wind got under
my
left wing and put the leeward wing down into the dirt at 15+ kts or so
on the roll out. Lost the wing tip skid but held it mostly straight
with
my big rudder.
I heard conflicting advice and comments about coordination and this
landing.
Sorry for the long post.-

POPS-

"Released rudder and flared" doesn't make sense.

The crab maneuver should be coordinated as previously mentioned. Rudder
neutral, string centered.

The flare and landing is what isn't coordinated. Downwind rudder.
Aileron into the wind as required to keep that upwind wing as low as you
can.

After a really tough pattern and landing on a very windy day, the pilot stated, "this is a really short field!", the co-pilot then stated, "yep, it is, but it's 5000' wide!"
