You read my mind. I was thinking of going this route too. Basically same price since I already own the tikka. I just hear good things about the triggertech triggers. That's where the ridgeline for $1600 intrigues me.
I would look at the Yodave trigger spring for the Tikka. I think it is like $15 shipped and will let you tune the factory trigger down below 2lbs if desired. Worth a try before you spend bug money on an aftermarket trigger or get rid of your rifle.
