I believe the powerup is interrupted by poise damage, not health damage. I think I did 47 damage per strike to him with a Lightning Reinforced Club, and he still staggered after two hits. 94 damage doesn't seem like near enough to disrupt him, so it has to be poise damage.

Long weapons are definitely ideal; even greatswords will do pretty well. Using the Reinforced Club I couldn't believe the number of times I missed the bastard because of its short reach. I'm not positive, but I assume the spears have worse poise damage than the club, but for anyone concerned, you can stagger him out of the powerup with two 2-handed normal attacks. I always thought it was a lot more difficult  to do, but it seems that most weapons can do it reliably, if you can get to him in time. Watch for that double roll back...it's one of his only very noticable  tells :P
