The only one I have flown regularly (B737 and B757) is Chambery 18 which is 4.6 deg.. very interesting.. on the 757 you have to be fully configured to land and back at Vapp before intercepting the glideslope because if you ain't you won't be able to slow down so it's a go-around... combined with the fact that there is no escape to the south cos there are rocks in the way .... go-around involves an 80 degree left then 260 degree right turn to escape to the north... straight in approach or circling.. you don't know which one you'll be doing til localiser intercept... fairly short runway.. VFR fixed-wing and rotary traffic all over the place... it's an interesting day out.
