But speed, in Bleach, seems to be derived from the character's spiritual pressure. His bankai seems so slow now because everybody is stronger than him. The whole SS fight between Ichigo and pretty much everyone in SS can probably be discounted by the simle fact that their pride stipulated that they'd never see him as an equal, and so never fought all out.
Zaraki aside anyway.... but even then, if he'd used kendo, Ichigo wouldn't be around right now. >_>
IMO that's the single biggest problem with this manga. Kubo just won't stick to his own power levels. I mean, obviously as he pulled out more arcs, everyone was gonna get stronger, but arranging any kind of adder outside of what's printed in the databooks is such a ridiculously convoluted matter that I honestly don't think any two people would come out with the same ranking tree >_>
EDIT: As for isshin's comment, I can see where you're all coming from, but it really is more of a spiritual pressure control skill. Most of, if not all of the current captains have been through Soul Reaper Academy, right? All of them would have learned to control and maintain their own spiritual energy before they called their shikai, and brought out the proper form of both their sealed and shikai swords. You can theorise that this would allow the maintenance of a proper size and shape for good combat use.
On the other hand, Ichigo didn't know squat about anything. That's why Zangetsu turned out so big, and why Renji was mocking the size of it when they met. And it's also why it used to shatter so easily, because he couldn't maintain the Spirit Pressure in Zangetsu either, meaning anyone with a more controlled output would just outclass it.
