Stranger,
Resting the barrel on the cross-sticks is the way to go. Accuracy, kind of like a long barreled pistol versus a short one. The forearm is attached to the barrel anyway. I could see interrupting the harmonies on a free floating forearm, but, it isn’t.
4-5” rest point below the muzzle, just so that you’re gun doesn’t fall or the sticks or damage to the front sight.
