I have one pair of skis that I use for everything and I have gotten a few coreshots early season and got those fixed and bases waxed. I haven't done anything since and my skis feel fine, I never feel like the skis are "slow." I have recently gotten another gash that went through the ptex whatever you call it, and I still don't notice any difference. What do you think if I just never wax the skis or sharpen edges (I could care less about sharp edges I ski in Utah) or get the goudges repaired when rock skiing season rolls around? All I care about is that my skis go forward and as long as they never cause a noticeable problem, why worry? I know they could get water damage and all that but I have already put in a number of days on my skis with this coreshot right along the bottom right now. The only reason I would take care of the bases is in the future if I wanted to sell them.
