I typically look for pole vaulters, just because of the time required to make a kid a 12-13 footer who’s never touched a pole before. I think there is a consensus on PV, 110’s, and Jav need to be worked first because they do take the longest to gain competence, but if I have a PV and 110 guy he’s the easiest to teach jav, because he likely has a fair amount of speed and he knows how to run with an implement. I personally have more trouble coaching shot to athletes than discus, the athlete’s seem to grasp blocking cues better in discus because it’s rotational visually while they are resistant to learning rotational shot and want to glide where using the same visual cue for blocking in the discus just doesn’t and won’t work in the glide. However, the athlete I always wanted to train is the discus thrower who can sprint or jump. I really think that’s the way to go.
