Harmonic Balancer

[gmhardwick66]

I am currently working on a 1968 C10 with a beefy SBC 355. The engine will see 5-6k RPM on a regular basis or at least every time I take it out for a drive. I am doing some work on the belt drive set up now, going from v-groove to a serpentine drive with an electric water pump. The current balancer is a stock 8" balancer. There is nothing wrong with current balancer but I want to go ahead and replacw it with a new one now since all brackets/pumps/alternator are out of the way. I have read up on the subject of balancer and dampners operation but there are so many on the market. I only want to spend about 200$ on new part. I have looked at the Professional Products 90002 Powerforce+Plus Harmonic Damper and like it. Has any one tried this 8" dampner and if so how is it preforming for you?
I also read up on PRW FluidGel dampner. It is not an 8" balancer though.
Any imput would be appreciated.
