good looks on getting some FRs, best ski out there.
When I got a new pair last year I just used a gummy stone (file works fine) and detuned underfoot for about three minutes. You don't need to do more than that, I would also recommend waxing the first couple of days on snow. ON3P has the best edges in the business so don't worry about them being less durable if you detune, they will still outlast almost any ski on the market.
Riding fairly new FR's in this edit↓and had no problems with edges catching.
