Wow! Really?
IMO any club fitter doing that really hasn't had enough experience in MOI fitting - or hasn't done it to their own clubs and then tried to hit them!
By suddenly introducing the term 'MOI flatline' you're suddenly introducing a straw man into this discussion. Other wise we'll need to talk about a 'SW flatline' as well...

By 'MOI flatline' do you mean that all clubs (wedges, irons, fairway woods, hybrids, driver) are built to the same MOI? If so, which club fitters are doing this? Flatline within one type of clubs.

But you seemed to discount the MOI method because the numbers would not be the same in each club type. pfff....again I discount MOI because of the so-called science based claims that go with it. I have repeated that now more then enough. To me the MOI machine is more accurate and I can build tighter club spec's using it. buy a digital SW scale and you can have the same precision. Did you include the changing cpm value due to head weight adjustment in order to hit the correct MOI value and made additional tip-trims to keep the correct flex? Do you know before you trim what the shaft will be like after the trim? Did you then re-entered the changed shaft balance into the MOI calculation to adjust for that? What I mean with the above is : How far are you willing to go in building to "tighter specs" and when are those xx digits after the decimal point still significant for the golfer in front of you. Doesn't a golfers swing axis have subtle changes with each club length? For instance a PW versus a Driver. well..again the MOI supporters claim the swing axis is the same for all golfers and for all length within a club type hence the fixed rotation axis on your MOI machine...... ----But again you don't agree with me and that's fine, if you are happy with the results and have no doubt then please continue. With the continued repeating of earlier postings and lack of others participating I feel this thread has come to an end.----

Frans I am an MOI supporter and I have not made that claim. I do understand what your point is and I did not word my question well as I was not debating about you using this statement to discount MOI. My point is that MOI fitting does have different MOI numbers for each club type and this is the same in your post using SW.
The digital SW scale can work but not all set's have the same SW slope. It is far more practical to use the MOI machine number to build the set's in my experience. The way you describe the 3 iron build the digital SW scale would work for the irons.
To your 3 questions it is Yes, Yes, and Yes.
I go as far as it takes to build the best quality club. How far anyone is willing to go is up to the fitter. It's time and money and what makes sense business wise.
Well if you want to stay on the MOI support claims that is fine but I was not asking about MOI or SW. You mentioned the Swing Axis fitting system you are working on and the question was aimed at that. I was interested and wondered if I was correct in my question. Can such a machine or fitting system adjust for the changes?
I have seen in video of fittings that there are small differences in players (talking about scratch golfers as well as mid cappers) spine alignment as they go from shorter to longer clubs (Wedges to Drivers). As the club get's longer the player becomes slightly more upright. When you fit for the swing axis does the way you fit compensate for a players swing axis change between clubs or are you fitting each club? Just curious Frans.
If you want the discussion to conclude that is up to you but it only takes 2 to have a discussion.
