Capsizing is fun... I am serious... It happens slowly, it is predictable, and it is not hard on sailor and boat. Everybody who sails a Hobie 16 will sooner or later capsize every once in a while - at the same time everybody should know about proper technique and equipment (bag/pole) to get the cat back up (preferably on their own)
Pitch poling is a completely different deal. Happens very fast - in some situations there is not enough time to react fast and sufficient enough to avoid a pichpole. Since the pich poling happens so fast it bears some risk of injury (it is most of the time the bridle wire that is in your way to the water - not mast or shroud) they are hard on the cat (severe deceleration) and you run the risk of turteling, which is way more difficult to take care of than a capsize (especially solo).
