I can see the benefits of Kbell training and intend on intergrating some more into my own training program but I can't see that it could replace pushing heavy wieghts. I've seen the guys down the gym who swear by them, one guy is a personal trainer who uses them daily and if I were to be totally honest I'm not that impressed with thier physiques and strength. I'm not saying that they aren't good because I think they are. It's just different. If it's big muscles you want it's big weights you have to lift there's no short cuts I'm affraid. The muscles have to be totally annihilated, fed and rested week in week out. Kbell develope a different kind of strength incorporating some of the smaller muscle groups which some might argue is better for MAs but for out and out strength they are always going to be second best in my opinion.
