I have not tried any of DeLoa's templates, only because I have never seen them used in person. I have Jamie's Mystical Mini with the notch for the foot (used for SID) and I really like the red handle. I am thinking I will get some of his curved rulers. Also saw a short video of someone using one of these for curved stitching and then the straight sides for straight SID. I will see if I can a link to that video.
