I have always been a sweeper, and never was able to play big, wide soles. Might be more of a picker than sweeper.
Played my best with those Lynx USA irons. Not too narrow a sole, although it was definitely had a sharp leading edge. Another head I really liked was the Maltby M-45, very low center of gravity in a smaller, compact head. The second generation POXG irons I have now is a little wider than I like with the XF model, but I am adjusting.
If I ever decide to go pure SGI again, it would be all hybrids. Had a friend who played them and I hit them a few times on the course, they just went straight. Ego was too big at the time to play them full time...lol
