Like BH said, a bit of the shimmies during spool up isn't bad. If you had the balls on your training gear vibrating slightly, I would lean toward a small imbalance somewhere.

How did you install the align blades? Did you use spacers?

Check your paddles, if they are slightly out of alignment you could get some wobbles and not really see it.

Did you have the shakes on spool up/down before your first crash?

I replaced my stock plastic head with the Kasama and threw on a set of radix blades. No vibrations. Sometimes it will vibe a bit spinning up, but its barely noticeable.
