I appreciate your response, @Westside. I'll check out your additional references.
Yes, I did read the first page and every subsequent page of this thread - it does detail different feel and experience between O1 and R1 throughout.
Unfortunately, I am looking for very particular information...I'd like to gather insight about one R1 radius insert and how it corresponds to an O1 default setup, specifically.
Example: R1 + H5-T8 = O1. It may be this simple, but I'm not an expert and that's why I'm trying to ask one. 🙂
