Like someone else said, it's totally personal preference. I can't stand the "gattling gun" sound a hopping foot makes, so I use a floating foot. I don't seem to mind whether it's open or closed lol. I wouldn't worry so much about rulers or any of that fancy stuff, just try different things and see what you like. Janome makes a really great adjustable FMQ foot that works on many standard low shank DSMs. They make a high shank one too, it works great on my Juki 2010. Good luck, your machine sounds like a really nice all-metal bulletproof one
