On Sturmey drum brakes; I I have little personal experience with the Dynohub version but the standard Drum Brake will toss you over the bars easily. I was so impressed I bought a pair (drum brake hubs) front and rear for an old Raleigh Gran Sport. No maintenance, clean rims, weather proof., strong large flanges, cool.
The standard supplied brake levers for the hubs suck however, they are nylon, are flexible and have limited travel and as far as I'm concerned, unsafe and non functional. We have sold hundred of the old Pashley Roadsters with these brakes front and rear coupled with Mountain Bike levers with zero complaints. My personal bike had Campagnolo record road levers and again you can easily lock up both wheels but they have better modularity than linear pull brakes. Linear pull a and disk brakes take less hand pressure to lock up the wheel than an SA drum brake but you have to wonder if being able to easily lock up a wheel is a good thing.
I would be surprised if the Dynohub brake performs any different from the non Dynohub version.
