Polls are definitely possible...

The one time I tried a fitting was odd.

Tech: Hit some drivers into the simulator.
Me: Ok. (hit about 5 drivers).
Tech: Ok you hit your driver about 200 yards.
Me: Um, no my average is 289 (calculated on the TGS game tracker)
Tech: Well this is based on sea level.
Me: I'd lose 90 yards at sea level? Wow.
Tech: Ok sir, hit this 6-iron into the net. Your ball is on a plastic swing analyzer which shows your divot pattern so we can evaluate your lie etc.
Me: Ok. (It a few 6-irons).
Tech: (picks up plastic analyzer and looks at my divot pattern) Hmmm, I've never seen one like this before. Hey Bob, come over here and tell me what you think of this.
Bob: (looks at my divot pattern)Hmmm, I've never seen one like this. Perhaps you should just go with a standard lie and loft on your clubs...
