The dozen or so TLMs I've ever been to have had their readings in the vernacular. All the other parts are either the same every time (or have only a few variations) or are propers (specific to each day).

I never studied Latin, but I don't find it difficult at all to keep up. A lot of churches that have TLM have the missal booklet with Latin on one page and vernacular on the facing page.

While I do appreciate the richness of the daily propers and miss understanding them, it doesn't bother me enough to avoid the TLM.
