Here are my favs. The top is my fav, then the bottom is least favorite.
1. BOMB It's really good for beginners, and since I love to go really fast and i'm good at dodging, I can hit people easy with this.
2. SCATTER Read the above.
3. AUTOMATIC This ring is really good when you have a lot of em'.
4. RAIL This is great for sniping, and it's fun to get up on high ledges and hit someone. They wouldn't have seen it coming! XD
5. GRENADE This is good for spamming, but it's annoying when people do it to YOU.
6. RED RING This isn't special, it goes slow, and is TERRIBLE for beginners.
I don't ever really use bounce, so no review on that ring.
