@dancing james does it really matter? I never understood why you'd want a fitter to draw the geo, that's not his/her job. Once you have your contact points established by the fit the builder can make the decisions regarding angles and tubes length etc...
I’d expect the fitter to communicate contact points to builder and the builder to come up with geo. It always seems odd when the customer specs geo - unless they are super experienced.
Think of the stability!
