You should do 28 35 50
15 is a gimmick. 21 might be a gimmick too
I have 28/35/50 as my setup for my OM-1n, and I'm mostly happy with it, but I often find that I want something wider. I shoot a mix of street, documentary and landscape work with my RFs, and when it comes to landscapes, I usually find I want something 21mm or wider, with a 50 or a short telephoto.
Edge, I agree about 35 and 50, they feel completely different to me as well. I know if I get a 21, I'd use it on a regular basis. Based on how I use my 17-40, I'd say 80% of the shots I take with it are between 17-21, and the rest are between 28-35.
I'd agree that the 90 framelines are too small on a 0.72 body, but with an M3 they're about the same size as the 50 lines are on a 0.72, which I wouldn't have a problem with.
