Does moving the binding affect performance enough to suggest that perhaps you would be happier with another ski rather than tweaking the design characteristics by moving your binding?
I guess I just don't get why you mess with performance characteristics that a team of engineers and elite sponsored athletes identified as optimal. I'm guessing that the percentage of skiers who can truly benefit from custom mount locations is very small and consists of true ski professionals and hard core 60+ day skiers. It seems to me that you have to be a very nuanced skier to truly benefit from this practice. How good does one have to be in order to tell the difference and make the right choices about alternate binding locations? I ski 30+ days per season and am a very capable level 8 skier, but I have enough inconsistency in my skiing from day to day or week to week that I'd think to tweak my skiing before my bindings.
What do you think Bears? I'm really interested.

I was surprised by the reaction of the lead shop tech, “we haven’t done that for 30 years”. This is from one of the best shops in my area that does a lot of racers. They set almost all their racers to factory marks. They are doing the BOF mounting for me but I thought I would see what other industry professionals had to say.
My boot fitter, same shop, said it is up to the tech but my fitter typically goes with factory marks.
I talked to a binding manufacturer, at corporate not a local rep, and he said it’s up to the ski manufacturer, they know best. This guy was involved with the original discussions mentioned in the above links going back to 2000 but has no preference.
I talked to a ski manufacturer, again someone at corporate not a local rep, he said it’s OK to do the BOF mount but they don’t think it’s really needed, they don’t really care.
Now this is one shop, one ski manufacturer and one binding manufacturer. But, based on the above links the preferred mounting position should be BOF for the best ski performance. However current industry thinking seems to be; the factory marks are a good starting point and make it easier for the shop. The factory marks are really a population average and should work OK for most people so why use anything different unless there are special circumstances.
What’s the current thinking of this community on BOF mounting? Is there anything to gain or is the gain so little why bother?
There is a lot of confusion around CRS/BOF.
As written above in the linked threads the "manufactured recommended line" on the skis....AND boots...is based on a generalization, of some generalized ideal skier. Its pretty good, but not perfect since we are all built different, (some taller, some shorter, some more mass in our shoulders, some more in our hips, different boot set ups, and ski stances) so there is no "one size fits all". There is room for optimization.
So does BOF/CRS work better? No. Its is just swapping one generic method for another. It might make you seem cooler to your ski buddies, but the value ends there.
So where does all the BOF/CRS hype come from? Was it all just a con? No. Let me explain.
Back in the day, when racing mattered....skiers would work to find their optimum binding mount position - and they would find it...eventually. So lets say for a particular skier, it was to mount 0.5mm behind the line. Next year...get new skis...mount at their optimum position of 0.5mm behind the recommended line....and.....it didn't work! Why not? Remember above...the recommended line is not consistent from brand to brand, and some cases ski to ski...so...0.5 behind might be ideal for ski X...but for ski Y...with a different line...it might be perfect at 1cm back or on the line, or 0.5 forward!
So to overcome this the CRS was developed...CRS provided a common mark that could be transfered across skis, regardless of brand. BOF was then created as it could be transferred across boots. Now...once you found your ideal mount point...you could measure it relative to CRS/BOF one ski/boot set up...and replicate this set up on another pair of skis/boot set up! Was it perfect? No...but it was pretty good.
So...to answer the question...yes there is value in trying to optimise...but going online to ask what works for others...is about as useful as asking others what boots they have...to get the same ones.
Best bet is to use things like a balancer...then use the CRS/BOF reference points to transfer the values to your skis/boots. Just swapping the arbitrary manufacturer lines, for another set of arbitrary lines, makes no sense. If you don't have access to a balancer or such...I'd say just go with the manufacturer's recommendation.
