There's also https://news.ycombinator.com/best as an alternative for a similar purpose. I learned about those two and other undocumented features from https://github.com/minimaxir/hacker-news-undocumented

You could also subscribe to HN on feed reader with such limitations, https://edavis.github.io/hnrss/ and http://hnapp.com/ are two that I have used in the past. e.g. https://hnrss.org/newest?comments=100 and http://hnapp.com/rss?q=comments%3E100 creates a feed limited by number of comments.

In the end I decided RSS wasn't ideal way to follow HN though, and for quite some time I have been using https://hckrnews.com/ almost exclusively to skim through top 10 posts for each day. Or top 20 or top 50%, if you have more free time. Plus I like the table layout, with comments/points in their respective columns.
