Slightly bite down into the RS a little below the tip of it until it is somewhat "balled" the angle the launcher to the left where the metal wheel is roughly 5 cm. off the ground when you set it down, bring the launcher up off the ground and use a good strong launch. The bey should bounce in the bowl around the other bey.(mostly because it is usually hit in the air w/ can hit it into the wall thus losing spin) The bey w/ Rs will then come in for an attack and usually get a nice hit. I hope you find this useful! BTW I have only tested this w/ 100 and lower so if it doesn't work try a 100 it works best make sure to make the bey light so it doesn't stay on the ground.
A great way to use an RS!
..... Biting into rubber, great idea! Getting some rubber into me and ruining a perfect RS that is now illegal.
Do not discuss illegal modifications, especially not stupid ones.
