This is the most fluffly and softest mallet I've come across. And it is a lot bigger than you might think, between a Paiste M5 and M6 in size (weighs about 220g). This is a mallet for gentle coaxing so it can get tiring and difficult getting bigger gongs to sing. Definitely one to try, it's quite interesting to use.
I'm adding this to the review originally posted. This mallet works really well for hitting gongs hard, especially the centre and you don't get the heavy dull resonance you can get when hitting the centre. As a result, you can get tones from the gong that have a completely different balance. Giving it a full 5 stars now.
