The ATI is held on by at least 6 bolts if my memory is correct..

From memory (which is poor), the ATI uses 9 bolts, all loctighted and 6 of them are taper heads for more sealing surface. I don't have any fear of it coming apart, and it is serviceable for long life. Having used both, the ATI is my preference though I personally run a Fluidampr on my car. You can't lose with either of them.

Completely necessary - that is up to you all. I would advise using one on a built motor, and heavily advise against the unorthodox-style crank pulley on a built motor.
