Kanonen is probably more intense but it's kinda over before it starts. Everything happens so fast and when it hit the brakes it's like ok, that's all?! Kanonen is an energy package that is over in 30 seconds and puts a smile on your face. Helix will be like the dominator, something you don't mind standing in line for an hour or 2 cause you will actually be able to enjoy it while riding, not just get off thinking "wtf happened?!" Kanonen is good, Helix will be epic lucky me living 15 minutes away from him
