Scherrit didn’t use any fancy video motion capture stuff with me. He uses Steve Hogg inspired methods. My rationale for choosing Scherrit was that in the absence of a whole bunch of personal recommendations, it was difficult to know whether someone using a Retul style system had simply paid out a bunch of cash for the hardware and a few day’s training, or whether they had a load of useful experience as well. I’m sure that the hardware can get, say, 90% of people a 90% good fit, which may be an improvement for many. However, I figured that if I was going to do it, I’d do it properly. So I opted for ~6 hours of experienced person time rather than a couple of hours of person time plus a chunk of hardware costs. I think that was the right decision for me (well, since then I’ve broken my spine so my flexibility has changed somewhat, so I guess I didn’t get great value from the fit!), but you pays your money, you takes your choice.
