I ride in no bike shorts with my Brooks. I think having a micro-adjust seat post is crucial with these so you can adjust the angle properly - so it doesn't jab you in the vadge - and you don't slide off like I did on my first ride when I came to a stop.
Once I tweaked and fiddled with it - it seems great! If it is comfortable now, I can't wait until it's actually broken in.
