The I+ factory tubes are good enough that you'd probably be fine with one of those while shooting the long beards. My gun threw some really great patterns with hevi 6's and federal HW 7's using a pure gold choke that I believe was either a .665 or .675 constriction. Sold it to a forum member to help him get his sx2 straightened out. He seemed happy with it so far based on what he's told me. I'll miss that choke but I don't use that gun for turkeys anymore.
