Do only the earlier Evolves have encoder issues? I got MEK with encoders, I was worried some would be flaky, but they all seem to be fine as long as I don't try to spin them like a top.
I do like the pots on my Rev2 and Pro2, but should I wait until they start failing before I upgrade to the pots? I was going to do it, but saw traces have to be cut and tiny SMT components are removed. I'm not afraid of soldering, but don't want to break it by fixing it when it's not broken.
