I got a chance to roll the Guru, Score and Yeti Uncaged at a demo day. Thanks Phil for coming out to Fremont Ca Cloverleaf bowl.
Guru- this ball is strong and I had a lot of fun rolling it. (Glad I brought this one home with me).
Score- Phil said if you remember the Brunswick Danger Zone this ball is very similar. My friend and I really had a great time using this one and yes it was like the Danger Zone. This ball is money!
Yeti Uncaged- this is the ball that I came to the demo for and it didn't disappoint. This ball is very clean through the front and just exploded on the back.
If you're thinking of trying Radical you can't go wrong with any of these.
