You probably hate it so much because you're just thrutching around in there. I had trouble jamming it, too, until I figured out I can just climb in like a chimney, with my left side facing the crack. Carry as little gear as possible, and sling it all to your right side. It's really just a few moves (for me) because I have long arms and once you can reach the top with your hands, it's over.
