I have a Voyager that came with both the standard foot and the Hinterberg foot. I have used only the standard foot so far, but want to start doing ruler work this winter. From what I have read on the net, the Hinterberg foot is not great and does not hop. The posts I have seen from those who do ruler work with the Voyager have all indicated that the Finishing Touches hopping foot is great; they leave it on all the time. So, I bought the FT foot but have not installed it yet. There is a Youtube video that shows how to install it. Depending on your machine, you may need to retime, which is one reason I haven't rushed to put the new foot on.
If you haven't yet done so, you may want to join the Voyager/Hinty yahoo group and ask there. You need to set up a Yahoo ID, but it's all free. Go to
