I like the finned x-wing   
 
 
edit removal.
 
 
I did see an x-wing and kite solution.  
 
 
oops   I missed an x-wing xyz-wing combination solution. [edit] |

				After the X wing a Type 1 UR  does the trick, and after
 
starting with the 147 xy wing a slightly different 
 
Type 1 UR also works- interesting if not elegant........ |

I used an XY-wing -147, which reveals an X-wing on 4.
