Bit late in the day to reply to this topic
but I have two Epic mid-wing paddles; one with the old-style length lock and one with an early release of the new lever lock.
The lever lock mechanism rusted up and eventually seized. Epic sent me a new one - entire collar mechanism - and I had it replaced. Then I had the old length lock replaced with a new one lever lock too. The old paddle's markings don't match - but that's ok I've marked it myself.
But I much prefer the lever lock - and since I had the new ones fitted, I've had no problems at all. Clearly the newer ones have a better grade of stainless in the fitting.
Just as a side note, I always rinse the paddles and lock mechanism after paddling...
