I like the Tikka quite a bit. But I'd buy the rifle I liked best even if it were a right handed model. The Tikka's tend to be very accurate, but many find the looks too modernistic. I think they look nice, but not everyone agrees.
My brother shoots lefty and tried several options over the years that were left handed, or at least easy for lefty's to use. He found none of the available options at the time suitable. He just started using right handed guns and shoots them from the left side. He is so used to doing it that he still uses them even though there are several good left handed options today. His choice, a right handed Tikka.
I'm right handed, but practice shooting from the left side. When hunting there are times when it is easier to mount the rifle from the left shoulder. With practice it ain't hard.
