I do not believe that any of us "enjoy" those approaches, like so many airports... SFO was built at a time of smaler, slower and less traffic and currently thats what we are stuck with. Coupled with terrain, cloud cover and lots of traffic it makes for "challenging approaches." Not sure what ATC would have you do if you refused...I'm thinking a break out for revectors or holding...just don't know. Our company gives us some guidance from FOQA to help in a more stabalized approach...rather than accepting 6000' and 210kts for a 10mile final, we request 5000' and 190kts. Prior to base be at 190kts and when turning final gear, final flap setting or the greatest flap setting you can use with speed brakes and slow.
