I can offer a few cents of knowledge too, I have three set up in the shop. First, compared to a T.S. kick back, a R.A.S. climb cut happens in slow motion and your first reaction is to try to stop it. That's when you'll have no idea or thoughts about where your other hand is, so always leave plenty of room between the cutting path and your hand. Also, whenever I see it, I strongly suggest that the operator immediately break the habit of sticking their thumb out towards the blade. (Opposing thumbs are nice to have, keep it under your palm.) I Like a 0 degree hook angle; if you're not familiar with the term, do a little research to find out why there are so many, and what's best for different applications. A lot of craftsmen like the R.A.S. for dados, myself included. These cuts are more prone to climb cutting. Most sets have a positive hook and frequently they are allowed to become duller than what would be acceptable for other blades. A lot of people say ripping on the R.A.S. is unsafe. I don't share that opinion. I find it more convenient and comfortable to use a table saw, but if none were available, I wouldn't hesitate. Done correctly, (the guard lowered and anti kick back pawls in place) with a sharp rip or combination blade, I feel totally safe.
