Default stock harmonic balancer question

I've been shopping for an underdrive harmonic balancer, and it's between the fluid damper and the ati, I'm leaning towards ati. I spin my engine up too a max of 6500, but usually I shift at 6200. some people claim that a fluid damper actually does a better job cancelling vibrations below 6000 rpm. but the General consensus is, any high rpm applications should use the ati.

any input?

also,I was curious, how good is a stock balancer at cancelling engine vibrations?

several posters will tell you the ati is the best but it costs alot. i felt any sfi approved balancer is an upgrade over stock , most are about half the cost. just my one cent.

ATIs are the best but IIRC they also don't recommend more than a 10% underdrive.
Every car in NASCAR uses an ATI.
Sometimes you can find a cosmetic blem on eBay, last time I talked to ATI they said that's the only place they're sold
