Mac,
Remember that you're not executing "impact" as a swivel or finish swivel. The feel of a HH to me is always more of a snap release with the longest clubhead travel, where I would contest that you actually feel MORE active hands. All of that being said, your best chance of getting it right (imo) is to monitor the clubface through follow through waggles. Do a few waggles to two arms straight and check that the toe of the club is pointing down the target line. I actually have a club with a tee glued to the end that serves as a pointer. (This drill while left arm and club remain in rhythm is fantastic for steerers)
Anyway, the point is to train your hands what their role is........this will give you a feel that you can duplicate. While HH is a hinge pin mounted perpendicular to the ground and your left arm and club is serving as the blade.................please don't think about that when its time to hit a ball. Your hands have a job to do and because you're on an angled plane, to get that toe down the line its gonna feel like a pretty substantial roll. Show yourself a few times where your hands need to go, then let em go. I remember Ted Fort talking about this one day telling me "you ain't gonna believe how reckless its gotta feel"
Right on my brotha from another motha!!!
Go make the tips of your fingers tingle in some no club/no joined hands practice swings...
