That's odd, I kind of found the reverse to be true. IF something's a metal driptip, I tend to switch to delrin or ultem. It's less heat conductive, so if I ever get a spitback (this is rare) I don't get burnt, and also, when I used to use ss driptips only, I would find they got gunked up way quicker than delrin.... This was back when I was dual using, and they'd get slightly moist and then get shoved in my purse, to collect lint and whatnot. To be fair I am much more focused on maintaining my setups appropriately these days with regular cleaning, but I still kinda have a "thing" about metal driptips. While it is as ugly as all else, I really appreciate the Siren V2 coming with that tiny plastic circle on top of the metal driptip. I also appreciate tanks that come with one of each.
I guess it's different for everybody....
