I received my switches from Novelkeys today. I'm currently using them stock. No films, no lube anywhere. Very low spring ping. Springs are moderately heavy, which I love. I roughly estimate that 50% of the top housings are a snug fit, and 50% need films. So, I will probably end up filming them all. To my ears, they do sound better than stock Durock switches. Quite smooth as well. If someone were to ask me which linear switch to use "stock" I would put these high up on the list with tealios and inks. I think they sound better than inks, personally. Nice switches, sir.
