Can't get rid of ridges in lofted body

I am trying to make an intake boot that must have specificgeometry to fit the application and have been able to get a decentmodel using lofts with guide curves. My problem with the currentmodel that I have is, I cannot get rid of some ridges that aredeveloped in the loft. I have tried making sure that each loftprofile has the same number of sections, adding connectors, andmanipulating the standard conectors with little luck. Reorderingthe profiles and/or guide curves has also resulted in littleimprovment. I can reduce the appearance of some of these ridges butthe ideal surface of this intake boot would be completely smoothand have no irregularities. I am currently using SolidWorks 2008SP4.0 on a 3.20 GHz P4 w/ 2.0 GB RAM and NVidia GeForce 7300GT.Thank you in advance for any suggestions.
