You seem intent on discrediting Trackman for some reason. Its no big deal to anyone if you're not goint to buy it. I'm just saying its the greatest thing ive ever seen in golf by far and have had nothing but amazing results with it. Also, I'll bet Flightscope is pretty good, too. So buy that one if you're worried about the price and data collecting. I really dont know the difference between them. There are very few people i trust and they said Trackman is the best so thats what we went with. I'm ecststic with the results. Putting a piece of turf down for a few swings doesnt seem like a big deal. There are sooo many things you can use it for that dont even require club data like approach tests, spin, driver fittings, etc.
