not totally familiar with your Versa Tool, but I like having a smaller circle to use for continuous curves, also an applique tool--several out there with different shapes so I'd recommend trying some out at a show to see which fits your hands best. I found Rhonda's S curve rulers harder to use, so sold mine and replaced with DeLoa Jone's curved cross hatching. I also like her circle ruler--prevents the flatness on one side that sometimes happen when you quilt around the side; and I've recently fallen in love with Dusty Farrell's Chubbie ruler--one side is flat, the other curved.
