Did 21 the other day and I have to say, you come awfully close to the high ground on the North side. We had a GPWS but good visual contact and the runway in sight some 9 miles ahead.
I absolutely wouldn't want to do it at night or in rubbish conditions though.
I've never done the offset VOR before, and this was my first approach to 21 and I was somewhat surprised by it. We spent a long time on the broefing, and were still not totally reassured.
