I approve of the build (although they shoulda found some way to open it w/o cheat). However, wtf is with the no drag. It's just stupid really. Guess they just though higher impact speed would mean bigger explosions... whatever.
Accuracy. Turning drag on meant that he'd have to fire a few shots to hit the target as the first round would've fallen short after burnout. With drag off, he can use the line as an aiming marker and get it on target.
Don't get me wrong, I'm not a fan of the guy either, most of his stuff doesn't fly without cheats and it's very rarely his own work as well. But, he's a big deal on YouTube and gets away with it.
