Well, there's all sorts that could be said about the title of this post but that's the name the Andrew Stephen Buck has given to G-Mat 23. This mat is something of an experiment so could turn out to be great or could turn out to be terrible. (I guess there's 'could turn out to be so so but where's the drama in that, eh?)
Essentially, this is a 200/70 Ubercat with a flattened rocker (perhaps its and Uberflat) and no rail hook so like I say, something of an experiment.
Either way, I can't think of a better test pilot.
