In reply to JimR:
Whilst the Big Bros are indeed an option, it would suffice to say that they are quite a specialist one, within an already specialist sphere.
The fact they're not available to buy within the UK, and that I've never actually seen one being used at a British crag*, further adds to my disinclination to include them. For the vast majority of our audience it will be a direct choice between the Camalot and the Dragon, as they're both readily available, and they're both good, so I think a straightforward, uncluttered head-to-head would be the best and most clear outcome.
Furthermore, I don't want to make life harder for myself than it already is. Climbing wide cracks is desperate enough even when you don't have to construct a piece of Meccano half way up it
*or maybe I have, but only once, and even then I wondered why on earth the individual in question was using them?!
