I tried a Hope Head Doctor. It wouldn't fit, as it's designed for ali steerers and the ID on the carbon steerer on my Ritchey Pro forks was too thick. I too am a fan of bonded custom bungs - in fact, I'm about to make another one for @Cycliste's new Cannondale, but it does require access to a lathe. On those occasions when I have used expander bungs, I've always got on rather well with the Deda double-clamp one. The Ritchey ones, on the other hand, are crap as the thread is too coarse.
