				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.
