jesper,
i moved the thread from the "notices" forum to the "fitters" forum. this is where you want your post to be. there is a
photo gallery of people who just attended one of our F.I.S.T. workshops. you'll notice at the bottom the names of two fitters, one of whom is in luxembourg and the other in essen. they are both seasoned fitters. they were good fitters way before they came to see us. they were trained in other systems and they already have big investments in tooling. i think it would be good to ask them, along with jeroen van geelen in the netherlands your question, because they've all been F.I.S.T. trained, Retül trained and so forth.
in my opinion it goes like this:
1. first, a fit bike that adjusts in an x/y axis and produces metrics that you can port into some kind of calculator that resolves frame stack and reach. it could be exit cycling, shimano, retül, purely custom, GURU. realize that i sell purely custom bikes so i'm biased. i designed the functionality of a number of these bikes back in the early 2000s, so i'm also biased that way. i think if you ask these fitters i recommended to you they'll say the fit bike is your first major purchase.
2. for motion/video capture, there are 3 things you need:
A) you need body angles measured.
B) you need a video taken (not just stick figures), for your portfolio, to show the customer.
C) if it's a major investment the output must be REAL TIME, not after the fact. you need to see the angles as the rider is pedaling so you can make adjustments then, not start, stop, start, stop.
but you don't need 3D! you are probably going to handle the other axis using other tools. for example, if you're looking at knee tracking you're probably going to do that with lasers, head on. so why do you need to pay for 3D when you don't need 3D?
i'm working with a couple of companies now trying to get the cost of real time motion/video capture way down, to maybe 1,500 or so. you need what you need, and no more than you need.
3. pressure mapping
geobiomized is sexy. just, what are you using it for? what are you trying to achieve? and more to the point, what drives your decision? let's take saddles for example. on my fit bikes i have tools for choosing saddles. either my fit bikes have clamps that let me very easily take off a saddle and replace it with another one, or i have a tool called a "switch it" that i can place on an older fit bike that lets me make a saddle change in 10 seconds.
i think you can see in this case what my "driver" is. it's not a pressure map. it's, "how does that saddle feel?" "it's horrible!" "okay, let's make a change. how does that saddle feel?" "much better!"
in this case the driver dictates the purchase. because athlete feedback and comfort is my driver, a big inventory of saddles and a quick-change saddle device are my tools.
i don't mean to cast aspersions on pressure mapping, rather to say that before you or anyone can answer your questions you must decide how you make your decisions as a fitter. this will tell you what tools to most closely investigate.
finally, you're doing the right thing. asking. when i search my fitters database i get 116 who use dartfish, 67 who use retul for motion capture. they all have their email addresses in their profiles. email them. ask them low long ago they made their investments and whether the investments paid off. what i don't have is a pressure mapping option on our profiles and i think we should add that.
good luck!
