coaster brakes can be excellent, the Sachs coaster as fitted to the old duomatic (on which the new Sturmey is based) is very good, i have a bike with a Sachs torpedo hub (with the same brake unit) and the braking's great, really powerful but good modulation (and it works just the same in the rain, unlike a rim brake) the old Sturmey coaster units were dogshit though, so if the S2C is based on a sachs unit it'll be great but if it's the old sturmey design again it won't... give it a punt i reckon, sturmey quality is way better than it was in the '70s (just not as good as it was in the '50s)..
