You are going to 'get your head bitten off' with a post like that. Not only is it totally random and out of place but it really isn't true.
Danny's vid was filmed very well, extremely well edited, perfectly fitting song. The riding was amazing.
Damon's vids are pretty much not any of this. They're basically low quality fisheye lens footage with someone saying 'fookin' hell' after every gap. His TGS riding is not as anywhere near as captivating, regular non trials riding viewers aren't going to be impressed with the same thing done over and over again and how're they to know if a gap / sidehop is big or not. (Please note i'm not putting down Damon's riding, how he makes vids or TGS, I'm just explaining why his videos are never going to be as popular as Danny's)
With regards to attitude as well as Luke mentioned, Damon has posted on here asking about steroids, he's had a few problems with selling parts to other users, he posted up a destroyed frame and had a general bad attitude with regards to that situation which all really has lowed his reputation amongst the forum and his attitude was probably (this is total speculation) why tartybikes didn't re-sponsor him when they did their overhaul of their riders.
Danny is a rider who is in a different league with every other rider. With his video, it was perfect to go viral and his excellent attitude in the media after that allowed him to go further and make trials into his career.
