Perfect Pitch Event Permanent?

IIRC, wasn't the same event just recycled with different fantastic rewards?

Something like that. Also, the event duration is explicitly stated to be 03/03/10 - 03/30/10 at http://maplestory.nexon.net/WZ.ASPX?PART...ageIndex=1. Unless Nexon makes a notice saying it is extended/permanenet.

As for what to get with those 81+ Pitches... if you can rush it, and it is beneficial to you, try for Wild Wolf Bandana because then you can show it off to everybody who did not/could not get it. Otherwise get a Chaos Scroll to use or sell for money, depending on what you need. If you are a chair collector, go get the chair and get some eggs since there is very little options after getting the chair. If you love risk, then get Clean Slate and/or mass eggs and hope for something good.
