OEM balancer or fluid damper?

Fluid Dampeners are not designed for cold weather. I have a solid SFI rated one on mine (I'm pretty sure its an ATI unit, but its been so long I've forgotten) so it won't fall apart. I think I've spent way more money on this 400~425 HP 340 street build motor but hopefully I'll never have a problem.

The silicone fluid flows at very low temps. I have heard this argument before, but I just don't buy it. It's not like it is full of 50W oil. And there is very little fluid in it as well. Regardless, my car only sees the road in the summer, so it won't be an issue.
