How durable are these? If if take decent care of them and re-sling at some point, will these still be on my rack in 20 years?
That really depends on how often/hard you climb on them. They're very durable and rugged as far as cams go, but if you're whipping on them repeatedly every other weekend I don't think any cam would last 20 years.
