Love the Alleycat and the DeepState. Both get played or carried with me every day. Both, although responsive/slimline, are totally different from each other. Highly recommend getting both!
Alleycat is great if you want a old school, but modern playability, type yoyo. Great for stalls and flip tricks. But can also barrel through your favorite midschool style tricks also.
Deep State is a killer everyday carry yoyo. Smaller than the Alleycat, a little slimmer. Fits in the pocket easier. Has a Large C bearing, can be setup to play completely unresponsive, or responsive. Great yoyo if you’re wanting to dial in your tricks. The thinner width and smaller gap will fine tune all your tricks. When you can hit all your tricks on this cleanly your tricks are going to be really smooth when you go back to your full size throw. Heard stories that Gentry use to practice his contest routines on a One Drop Dingo.
