The only issue I had during the fitting, and this is most likely to be limited to a very few, is that I found the platform to be too small for me to hit some shots with my normal swing. It is really a space perception issue for the most part. I almost fell forward off the platform. It wasn't difficult to keep my body from moving forward, but if I wasn't paying attention I could have fallen. Moving back on the platform was really not an option because it gave me a false optical illusion. I am accustomed to hitting indoors, but this was the first time I hit off a platform. I would have felt much more comfortable hitting off the floor level. I don't know if you could have produced the amount of quality data from there.
