I have not tried the Shake…but own the two YYFs. So I’ll compare those two.
The Space Cowboy are Shutter are quite different in terms of play. The Cowboy is the one of the smoothest yoyos I’ve played. The weight distribution that the stainless steel rims makes it very stable. Right out of the box, it is one of my longest spinning throws.
Below are some pictures of the Cowboy and two SuperNovas (2012 and 2014) for comparison. You will notice they are mostly shaped the same.
The Shutter is more like a swiss-army knife yoyo. Grinds, finger-spins, horizontal and anything else you can throw at it. I tend to play my Shutters more than the Cowboy. In my opinion, it’s the more chill one of the two while the Cowboy is all performance.
For another comparison, I picked the MYY N12. It gives me the same vibe as the Shutter. (vibe as in feeling, both are smooth :-P)
If you are still reading by this time, I’ll give you my recommendations. (Sorry for the long post)
With your budget, I would pick-up a Shutter AND a New SuperNova. I’m suggesting the SuperNova over the Space Cowboy because it’s cheaper and plays similar way. The price for both would be $120.00. Same price as just the Cowboy. You can even buy some response pads and string with any money you have left.
You enjoy either that you choose.
