				| Ted, 
 I accidentally deleted your message while trying to clear my erroneous response. Please re-post your solution!
 
 Bottom Line: Your W-Wing solution is correct. I posted this puzzle as a "fun" XY-level puzzle.
 
 Regards, Danny

 It was certainly fun!  As often happens, I found a longish chain instead of a short-and-sweet wing.  I guess it counts as an XY chain, if you don't mind the strong link on one end.

				| Danny, it makes me feel good to know that others sometimes mess up also.     
 w-wing (18)r3c4+r7c5 with SL (1)r37c6; r3c5, r78c4<>8

				| The W-Wing was pretty apparent. I thought I screwed up because I was expecting a more complicated solution. |  |
