yo man i went when was 14 also at the time i was could a little more than what you have said.. looking back now, i wish i waited because i think i would appreciate going to windells more now.
i would suggest waiting until you can do more before you go to windells because you will be able to have more fun when you can truly shred windells.
im 17 now and wish i could go back but i dont know if i will be able to spend that kind of money again.
PM me if you have anymore questions
