I dislike bipods on general principal so prefer to not use one. I can shoot with a sling and sandbag support or I can use a pedestal rest with two feet (BI-pod) which is loosely attached to the rifle (lanyard). The whole bipod thing is antithetical to the original intent of "F" class. The original rules called for any rest, other than return-to-battery, including a sack of horsefeathers, if so desired. Unfortunately, just as nature abhors a vacuum, people seem to abhor simplistic rules so here we are. Regards, Bill
