No pro, but I believe the answer to be rake. Can't give the scientifics of it, but go back to the old school choppers or a raked out chopper like this pic. Comfortable and stable at relative speeds, but in extreme builds, the suspension was the raked out front end - in other words you had long enough front ends, that the forks themselves would bend, rather than compress, and absorb the bumps in the road. Look at sport bikes now, short, compact triangles, no flex but rather compression. Which turns better? Trail isn't about how far out the wheel is, but rather how far off center the forks are to the axle - in front of it or behind it. Rake would be the first thing to dial in, then trail.
