I can recomend the T/C Omega. To me, it is perfect with open sights and still allows you to mount a scope at a later date. I had a very hard time getting my head down low enough with the Triumph. That gun seems to be better suited for a scope. The Encore, although I have never shot one but have shouldered them, seem to be fine with open sights too. The Knight Rolling block seems to be better suited for a scope too. No experience with the Knight Extremes though.
