typical responses for someone of your age (if that is your real Birthday on your profile) your still wet behind the ears, ive been riding 11 years now and have seen many changes in trials some good some not, i ride how i want to ride so dont say to me what or how to and to ask myself why i ride i was basically trying to say do what you want to do and dont and not what others do if thta makes you happy, i guess i dent explain tyhat very well. the vast majority of my friends are not bike riders but what i would call everday folk who look at what we do as an extreme sport basically because its different andd not mainstream. Like it or not trials is "cool" right now and many people on here when they reach 17-18 years old will stop riding once they can drive and drink in pubs etc or just simply get board, i have seen this happen many times and will contiune to do so this is why i used 16 year old as an example.
Also you can use what music you like and when you have the editing skills and riders to go with it you can. i have an old GT video somewhere with Hans rey riding to send me an angel by real life. it was a promo video around 1991
