Would a hinged club help?

Basically I am looking for something to really groove my swing. Most of the time my swing is good and I make solid contact with the ball, even taking divots in front of the ball (impressed myself with that one). However I have these cycles of "ruts" where I'll skull it, hit it thin or fat several times in a row. These cycles have been the single most frustrating bit in my game. I'll play 4 or 5 holes well (pars and bogeys) then I'll go to playing 4 or 5 holes like total dookie because of successive mis-hits. I've eliminated some of this by really paying attention to my setup and routine but it'll still creep in.

Now, I went to the range last night and something interesting occurred. For some unknown reason my wife came along with me. I went through the first dozen or so balls with my usual routine and was hitting well, then the bomb dropped. My wife says, "I'm bored. Are you almost done?". I look down at the bucket and there is still a good 60 balls left. So in order to keep my wife from driving me nuts I decide to try and speed up the pace a bit. Then the mis-hits begin. I must have mis-hit 30 balls in a row. Not all was lost however. The last 20 balls I calmed down and just took 3/4 swings with good results, so the practice session was not a total waste.

So I'm stewing this over on the way home and the light goes off. Something in my swing breaks down when I feel rushed or pressured. After putzing around the internet it would seem the best thing to really groove a swing for repeatability and tempo would be a hinged club so if I rush any part of the swing I'd get instant feed back. Thoughts?

I have heard of people using a metronome to ingrain timing.
