I don't see this covered very often (okay, never), but I do hear people talk about how far back you should go with certain irons. For example, the idea is that you wouldn't take your PW back as far your driver. I guess my question is, what constitutes a "full swing" for a PW vs. a "full swing" for a driver? Or a "full swing" for every club in the bag, for that matter? Is there any sort of general rule of thumb for how long, or full, of a swing you should take with the different clubs? Of course, I'm talking about just a stock shot, not trying to do anything special.
