Mehhh, it take a lot of work to get really dialled in on building a pair of skis. Sounds like Surface is trying to clean up their name and quality a lot over the past few years; and I've never heard of them leaving someone out in the cold with warranty.
Regardless, I wouldn't stop an isolated incident like this stop me from buy a pair of these blanks. $250 for a price-point ski, made by a legit company with a wood core (not cheap foam core crap...) is a steal IMO
