Modeling a bottle and having troubles with loft feature

Hello All,

I'm trying to model an A1 steak sauce bottle in solidworks 2012. I believe I'm on the right track and I'm very close but still not there. I'm currently trying to use a a 3dSketch as my base profile and the second profile is a normal sketch on a created plane. The guide curves are all normal sketches on the respective front and right planes. My problem comes when I go to do the loft I don't get the smooth loft that i was expecting. I've tried converting the guide curves into a 3dSketch but that hasn't helped. I've included an image of the bottle I'm modeling, a screen cap of where I'm at and the file as well. Please help!
