I just bought the water lily, I like the size and appearance, and it has a 4mm bearing as opposed to the black silver and blood which have a 5mm (width). So far, I HATE how responsive it is, but I just ordered a ton of different response stickers, and I am going to try to rig up some sort flowable silicon. euro-yo.com is the only place that carries the water lily, and the owner is very nice. It runs about 70 pounds ~$105. I got it in 9 days. Remind me, I’ll let you know how the other response systems work. But, it is a great size, shape and weight. If I can get the response right it will be perfect, and the finish is like silk.
