I have been playing the X-Yo straight out the box and it IS the quiet-est yoyo I own. I would also expect it is probably smoothest yoyo I possess. The axel is tiny but the bearing seat design is very good.
well, I don't think anyone has played the MFHZ in aus yet, but I would say go with the Hitman because it'll probably end up being a better yo for the money, just think all you need to replace on the hitman is string, with MFHZ it'll be friction stickers and string.
But if your willing to wait for however long it is till someone can give you a review on the MFHZ then feel free to wait, just remember that if you buy the hitman now you may have enough time to save up for the MFHZ as who knows when they'll get here. . .
