Yep. Responding to the OP of a 3+ year old post is ridiculous but posting to a thread with a lot of good info isn't if the topic still relevant. In my case, I got here because of a search and basically there are a lot of great posts to the question I was wondering about...is there a point where terrain gets too technical for clipless? The short answer is "no, but ride with what you're comfortable" and there are a lot of good arguments for both sides.
