Jebs are the best chokes and best service I have found. Shooting Berettas the .650 normally does really well with HTL. Was struggling with patterns so Jebs sent me the .655 and .660 as well. Told me to see which one was best and mail back the others. The .660 was the ticket.

The 18"-20" is awesome with these patterns as well.
