Ask any material scientist. Unless of course you delaminate them.I'll call BS on that.

Wood core? Do you tune when there is ice, setting both edge and base bevel angles? Polish with diamond stones?The material scientist will sell you a bridge in lower Manhattan also.
I have several pairs of FIS SL where the cambers been beaten out of them. Literally dead flat under foot. No rebound. Lose of torsional rigidity. Won't hold on ice anymore. No, they are not delaminated. no fan fare. No funeral. Just dead. Happens about 70 days of free skiing. Not racing.
your ski collection are more akin to tinder action on Friday night....

Desire? Often! Especially in clothing. Probably a case of “retail therapy”. But being small and skinny, it’s really hard to find ski attire that fits me “right”. Always some part is too short or too big... Off to buy some new ones!Just how often do you feel or have the need or simply the desire to change to new equipment?
Many frequent skiers seem to get 5 years use out of a head lid. Trying to get two seasons out my helmet that I got last year is a stretch. Need to open and close the vents via a screwdriver as the switch got ripped off playing in the trees. Normally the stink factor as the spring approaches is the killer.
Yeah, using an edge grinder will limit the life of the edges. I have never had a problem with hold using a good sharp hand file. Three passes down the edge will usually make them so sharp as to be hazardous on the way from the parking lot to the base lodge. And btw, here in the east where "eastern packed powder" (aka ice to westerners) is common, I sharpen every other day, even every day, if needed. But we can also go weeks with hero snow and in that case I do not sharpen at all. The test of the ski in my opinion is whether or not it holds on the surface skied, carves well, and doesn't do any crazy things at speed. Of course the ski industry will promote the urban legend that you have to have new skis every year or every 70 days on the hill. That is what they are in the business to do.Yup, multiple pairs of Atomic FIS SL over the years. I send them out at the start of the season for a base grind and base bevel - 0.5 degree. Verify the base bevel when they come back. Clean up base bevel at the tip and tail. Set the side edge to 3 degree with a edge grinder. I find the edge produced by the grinder to hold better on hard pack & ice than a hand filed edge.
I used to hand file and polish with diamond stone - up to 600 grit. I don't race so grip is more important to me than time. It's a tech ski anyway.
A very standard routine for us at the start of the season.
I have multiple pairs of the same ski. Whether they are race or all mountain. I can tell the older ski once it get pass about 60 days. Just have to ski them back to back.

Right. Hard to believe since one checks after every pass of the file. That doesn't meet the machinist's eyeball test. You imply that you sharpen at the beginning of the season and that is it?The edge grinder actually takes off less edge material than a hand file. YMMV.
I run out of ski long before I run out of edge.

... it's better to buy used bindings when they are still on the race skis..there is a better chance there are no missing screws.
I built wood waterskis. They warped within one season. As an engineer, wood has many wonderful properties but stability over time is not one of them. There are lots of small cellulose fibers carrying loads - but these fibers are not as strong as fiberglass or carbon fibers and can deform or stretch easier. Wood certainly can and does move over time.Just an observation. Many race skis have wood cores, and wood core skis do not lose pop over time. Bases wear and edges get too thin, but if you have a quiver of primarily older race skis they should last you a long long time. OTOH, there is always that urge to try something new ....
Eric, you I am sure are familiar with the purpose of the core? It is simply to bond the top and bottom structural members together, right? Not to provide stiffness itself. For instance, it was not too long ago that Atomic was using foam rather than wood in their SL skis.I built wood waterskis. They warped within one season.

Wood can be constrained by composite skins so a wood ski can be as durable as the composites in the skin. The epoxy in the skins can get some creep over time and use. Individual fibers of glass or carbon can be overloaded and fail without all the skin failing - softening the ski over time. Small delaminations happen. Skis age.
With that said, we test "dead" old waterskis. Surprisingly, they stiffen over time. The thinking is that the epoxy gets harder with age. The "dead" feeling is more associated with the ski getting stale for the skier's skills. Buy a new ski just to keep your skills sharp!
