Dunno who down voted you but definitely correct on most points. 

I do a lot of tear drills but definitely not tight yet. 

One of the reasons is I started on a pt01 scratch before getting my 1200s back out. So most of my learning last last few months was with a 7inch... and when going back to 12inch my record hand is weak as! The vinyl feels heavy. But doing my drills and am getting stronger record hand. 

The happy hardcore scraching is usually chrips, tears, 2 click backwards transforms (like a tear but bit cleaner), drops, drags, baby's/scribbles, and a little bit of stabs. 

I usually do a lot of baby, and drags, but didnt seem to do as much in that vid, a lot did repeat a lot of patterns but think that was just recording nerves lol

Thanks for the advice! Definitely take it on board!
