I actually have a pair of Sunrise I have had since Worlds and I am really really enjoying them.
Bearing size in 2A yoyos is funny… Specifically to Sunrise I find the biggest difference is a very real ‘snappiness’ off each loop. In some ways it feels easier to control as you loop faster. You also can feel it hit the end of the string more in my opinion. There is just something really pleasing about how they control. There is also something subtle in how it ‘sleeps’ and then loops - many people loved the YoYoJam sunset trajectory and how it looped was pretty unique so this is an effort to bring some of that magic back. Looping more than 1A is a very personal experience in finding what works best for your own style.
Maybe @Dave_Geigle could weigh in!
