Thanks for pointing this out, as I have some RARA V2 coming, and it is good to know this. Maybe the issue can be addressed somewhat.
I had Penguins but I didn't notice any excessive noise before I sold them. Most tactiles have ping, you just want to avoid the ones that have a real problem with it [e.g. Dragonfruit] or lube around it [Everglide Jade, OUTEMU Sky].
I think one aspect behind the popularity of the Boba tactile housing is that it sounds good and seems to ping less-than-average.
Lubing those Durock Medium Tactiles is somewhat of an involved affair. [Penguin, RARA, Taro Ball]. Too much / too thick and it can get sluggish. I recently watched a review of the Penguins wherein the distributor apparently suggested using a light coat of light lube, GS1 specifically, including on the tactile legs.
If using a light lube, then lubing the legs smooths the bump and eases post-bump transition. Without lubing them, you just get a 'catch,' a slow-down in the operation of the switch that isn't satisfying. This is with light-lube, mind you.
If you are using a heavy lube like 205g0, then the Canadian distributor of RARA V2 does not recommend lubing the tactile legs, as that could excessively reduce tactility. All the evidence I've seen is pointing to use of a light lube over the entire stem and all contact surfaces of the switch. Although you can lube with 205g0, here's one person's RARAs:
