Having had practiced with Newton for several months, I had begun to realize that it doesn't have enough control for what I wanted to do. So I had read on some forum page that Newton uses many features of FVDs, and that FVD's give you complete control of your coaster. I tried FVD eFormulas, and at first they seemed extremely difficult to use. After a while I began to love what I hated, and now I have a fair understanding of Force Vector Designs. [:D]

FVD users only- tell me what you like most about FVD's and the biggest problem you have with it, and how you fix such problems.

Non FVD users- tell me why you do not use FVD's and if you have tried them or not.
