Thanks for your quick response re. the question.
I raised the question both for personal education as well as where the optimum mount point for my personal use of Atomic Coax 183's would be.
The use is stricktly for sidecountry and pow days. No park/pipe, or the like.
Over the years, I have found that boot center mark agrees well with the mfg's suggested mount point as silk screened on the top skin. [after verifing w/ a tape measure] [traditional ski designs]
My foot length/ arch location is proportionately normal so there are no shell length compensations for anormalaties, and shell length varies 314-316 from Nukes to RX130's.
I'm a "babe in the woods",,,or rather,,, "an old buck in the weeds" on the subject of twins and current design, and do not want to get left behind,,ever.
Thank you for your kind consideration and knowledge which I interpret as greater than you admit to.
Feel free to expound regarding general knowledge on this subject. I'm listening........
