Tikka without polymer is a Sako (maybe that's a stretch). I looked at the Tikka and didn't really like all of the plastic. I have an old Sako L691 (pre-Beretta) and I would spend extra money for a Sako, but that's just me. I'm sure the polymer holds up OK, I just don't like it when it comes to mags and trigger guards.
My vote would be not to Tikka.
