Ok.. i haven't ridden many decks only a pro model and an old A.I have been ridin the old A lately but yesterday i switched back to the pro cause my wheels are wearing down and i needed more ground clearance. anyway i noticed that the pro is absolutely murder on on the ankles if it smacks you .the old A isn't nearly as bad. i just wondered if anyone else found that some decks are "friendlier' than others.by the way i can't just toughen up,i'm old so it takes me twice as long to heal,and quiting scootering is just not an option. i'm addicted.
