Now, before all the hotshots on the board tell me they get in more than 15k a day, let's remember that Lostboy is talking about "typical" skiers, not the people who participate on this board. I think 15k may even be overstating it.
That's why its so difficult to provide a good answer. Injected foam core skis are, I believe, the least durable construction usually reserved for the low end of a ski line as opposed to milled blanks or wood cores. However, if you huck cliffs a lot or are a mogul fanatic even a wood core ski like your K2's will not last long relative to what they would if used mainly on groomed runs.
100+ days is a figure often cited as an average for wood core skis but again its highly dependent on their use. Others here may be able to refine the answer better. However, I would suggest that one measure would be that if a ski with otherwise sharp edges and a flat base can no longer hold an edge well on hardpack where it could easily before, it is time for new skis. The existing pair may still work well in softer snow though.
There doesn't seem to be a lot of quatum changes between last season and this one in a lot of ski manufacturers lines. So, if you think your skis are near the end of their useful life, it may be a good time to buy a pair of last season's skis at 40-60% off as you are considering doing. Just swap out your bindings, if you can find a flat as opposed to "system" ski.
