Yes. Although these are pretty darn smooth in their stock form, we believe re-lubing them yourself will allow for greater consistency in smoothness. We recommend using a light application of Krytox 205g0.

If you don't have a lot of experience with spring weights, we usually recommend going with a lighter weight as a starting point. You should enter this hobby starting lighter and then going heavier if desired, as opposed to the inverse (to avoid unnecessary strain). It should be noted that 62g is not even very light to begin with.

If you spring swap, the only difference will be in stem color. In which case, we quite like the dark green stem that comes with the 67g variant (cock-sauce switches, anyone?)

No, these switches were sourced from an authorized distributor in a newer batch. However, we also tested and approved each of our batches for stem wobble issues, out of precaution.

From what we've checked, all our Tangies contain a double-digit mold mark on the bottom housing. We are mentioning this because there was speculation in the community that single-letter mold marks were an indication of the batch being possibly defective, but please note this was purely speculative. More than likely, double-digit mold marks simply may indicate a newer housing and stem (à la Alpaca V2 instead of V1).

If you haven't heard about the defective batch, please read more here.
