What is the advantage to adding a ULT to a Tac-One?

[MnSparky]

I have a Tac-One, and I was interested in adding the ULT. What are the advantages? Is it worth the money and potential problems? Thanks a bunch for any advise.

Lighter trigger pull. I like it. Have it on my gun. Haven't had a single problem yet. Been used in warm & cold weather.
