I don't like that the use needle bearings and do not have direct oiling. I'm curious if any has actually used them.

Needle bearings aren't necessarily a red flag. Morels are really good quality lifter, and their street solid roller lifters use needle bearings and are very streetable and durable, I've run them before and never had one fail. And I even ran them a little high on the spring pressures than they recommend.
But just like with Harlan sharp rockers which use needle bearings, not all bearings are equal. If the race is not hard enough.. those rollers will eat through it. But think about this.. we're talking about a roller wheel which is absolutely harder material then a rocker bearing race.. and lives just fine rolling on a Billet lobe
