MalletGod

4 years later, let me answer! 1. The vibe mallets are good, but can muffle. 2. Don't really like the marimba mallets, the head isn't well attached, and I prefer ones with yarn securing the head. 3. No, you don't need special mallets, I use marimba mallets

Yes! I have used them! The Jim Cassela medium vibraphone mallets are sturdy and create a nice resonance, but they can muffle the sound slightly. Hard mallets however can damage the instrument. For versatile marimba mallets I recommend WNSC white and red wrapped mallets, https://www.amazon.com/Percussion-Mallets-Portable-Keyboard-Instruments/dp/B092VL5QLZ they can also be used on vibes if you want and can be used on sus cyms. For vibes, I recommend Musser, but any mallet with an egg shaped head is good. However, try to get one with secured yarn and a well attached head. In the end, it is up to your playing preferences.
