Full Choke Mossberg 535

I thought I would ask the question,  which shotgun choke do you all like to use for turkeys ?

I will be shooting a Mossberg 535, 12 gauge, using 3 inch turkey loads  from federal, and I plan on using the full choke that came with the shotgun.

It holds a very nice pattern at 40 yards , I can't really justify spending $40 on a XX turkey choke...

 What's your experiences with  the full choke ?
