The whip is one of those EL cheapo beginner yo yos but as my first unresponsive yo-yo it brought me pretty far.
you can check out the specs on YYE but it has a C bearing and silicone pads but is slightly responsive and does not tolerate alot of layering which is very aggravating in more advanced tricks. It is also very light 54g which i think is great for getting the feel of a yo-yo on string but without the momentum the spin time is cut down(another pain).
I know Ann Connolly uses one from time to time but her’s has a concave bearing which prevents the string from causing the yoyo to tilt (which happens constantly with the standard flat C). Also she is crazy good and is used to using higher quality and heavier yoyos so don’t let the videos fool you; it is a difficult throw to pull off anything past a spirit bomb with.
But as a beginner or intermediate player this yoyo it is absolutely fantastic.
Pros: EL cheapo, fairly unresponsive, light (if you like that kinda thing), versatile Ie. grind grooves (grinds are possible with this yoyo).
Cons: Light (if you hate that kinda thing), semi-unstable, fairly short spin time(1-2 minutes), not great for very advanced tricks
Final thoughts: great beginner yoyo highly recommended, buy one if you want to learn from good ol Andre Boulay, and get into the yoyo world.
