After coloring a few times, I needed a long xy-chain to eliminate the 9 in R2C8, which solved the puzzle. Anyone do it without a chain?

Earl,
The hint is in the title. It is a lot of (XY, XYZ) wings.

That was too subtle for me. The sledgehammer approach works better. 
I used a W-Wing, an XY-Wing and then an XY-Wing with pincer coloring blew it wide open. |

After the basics:
| Code: | +-------------------+-------------------+-------------------+
| 8 7 4 | 1 9 6 | 2 3 5 |
| 69 1 2 | 5 3 7 | 46 49 8 |
| 369 5 36 | 4 8 2 | 67 1 679 |
+-------------------+-------------------+-------------------+
| 67 8 9 | 3 467 1 | 5 247 2467 |
| 4 2 367 | 9 67 5 | 367 8 1 |
| 5 36 1 | 2 467 8 | 9 47 3467 |
+-------------------+-------------------+-------------------+
| 37 34 5 | 8 2 9 | 1 6 347 |
| 1 3469 367 | 67 5 34 | 8 2479 23479 |
| 2 3469 8 | 67 1 34 | 347 5 3479 |
+-------------------+-------------------+-------------------+ |
A beautiful XY-wing <367> takes out <3> in R789C2. Leading, after some work to another nice one:
| Code: | +-------------------+-------------------+-------------------+
| 8 7 4 | 1 9 6 | 2 3 5 |
| 69 1 2 | 5 3 7 | 46 49 8 |
| 369 5 36 | 4 8 2 | 67 1 79 |
+-------------------+-------------------+-------------------+
| 67 8 9 | 3 467 1 | 5 247 2467 |
| 4 2 67 | 9 67 5 | 3 8 1 |
| 5 3 1 | 2 467 8 | 9 47 467 |
+-------------------+-------------------+-------------------+
| 37 4 5 | 8 2 9 | 1 6 37 |
| 1 69 37 | 67 5 34 | 8 2479 23479 |
| 2 69 8 | 67 1 34 | 47 5 3479 | |
<479> takes out <7> in R46C9.
And, <347> takes out <3> in R9C9.
Finally, an XYZ <479> takes out <7> from R78C9.
The puzzle is done! Very good wings, I thought.

In the initial grid there is a Kite (pivot b4) that removes <3> from r8c9 and makes the final XYZ Wing in Keith's path unnecessary.
