Sure but what works for you may not for others. I never even came close to any varsity team in high school let alone a scholarship to college so we're already talking two different levels of athleticism.
Online instruction and cheaper cameras make instruction more than ever available to more people now.
I agree, thats why im saying you have to take whats in front of you, try it out and see if it works. If it dosent, your out nothing but a little bit of time and no worse off than you were before. If you can afford lessons, by all means go for it, I think that its awesome that our sport has instructors to help everyday joes like us instead of having to be a high caliber athlete. And, I don't think you have to be a seasoned athlete to take the route of trial and error, just have to be willing to accept that some things wont work for you and be able to erase it from memory, which I am able to do. I hope that one day (when the FD starts paying a little better, lol) I'll be able to take formal lessons but for the right now, all I am able to see is "McLessons" and thats what I have to learn from.
