Replying to Longest you've kept your skis?

I thought this would be a fun question to ask: what's the longest you've kept/ridden a pair of skis?

For me, I've had my 2009 Line Anthems since......well, 2009. They're in relatively good condition still, only minor scratches on the topsheet, and a couple small gouges on the bases. Compared to my brother, I also don't push myself as hard to land new tricks, which also might attribute to their condition.

Recently though, I've wondered if it's time to look for some new park planks, as I feel like a stiffer ski might help me progress better. Although, I could probably overcome that with practice.
