Prior to my LB wheels I had a set of Yoeleo’s. They had the internal nipples with sealed rim bed. Never had a problem with them but it was strange how one was finished and clear coated/sanded and one was less so. Turned me off a bit but to be fair I run tubeless so I didn’t have any worries of tube rubbing against a rough surface or anything, just me being weird I think. At any rate, I wouldn’t think twice of using that option on my next set of wheels if it was available, like the others mention it wasn’t an option when I bought my LB’s. I don’t mind wrapping tape for tubeless but the odd time where I noticed I was losing air in my tubeless faster than usual was due to the tape giving up to the pressure at spoke hole
