I have never rode one.. me be chicken...

but i can see how they would be helpful for stress and the like.
Basically for the reasons you are experiencing.
My question would be..
what is the long term effects of going at that speed onthe brain?
Our circulatory system requires a certian "PSI" to sustain itself.
changing that so drastically again and again cant be good for ya?
I am not talking about the occasional ride..
Im thinking once a day.. long term...?
