It seems like original v1 pulley caused some issues but I haven't come across much actual talk of it. I guess it happened a while ago and they've come out with a new version.

Are there any reports of issues with the new version?

 

It's not balanced.

Get the RPW one instead. Much sounder investment.

the link explains the risks using a pulley that is not balanced and dampened.
RPW is advertised as both balanced and dampened

 

I see it being labeled as balanced but not dampened. I don't see how it could be manually balanced unless it came with counter weights or material removed. Also I don't see how it could be dampened if its made of solid aluminum. Doesn't it need some sort of mechanical property for it to dampen?

 

Months with the V2 and not problems

 

it has the same properties and characteristics as the stock pulley which is also a solid piece of metal. RPW's is lighter. by 3.5 pounds i think. during the group buy at the 9glancer forum one of the member took it upon himself to check if it was dampened. he received an email from rpw confirming it. its in the rpw group buy thread.
