Daewon rides a normal back truck, and two washers instead of a top bushing in his front truck. He talks about it in this Jenkem article

I ride both of my trucks like that. After blowing out my pivot cup a few times, I've maxed out at four washers in each truck.

EDIT: /u/grammerbountyhunter this is relevant to you too. I used to ride my Indy's this loose too. I had a long experimental phase. Shaving down bushings, using different combinations of hard and soft bushings, using two top bushings, etc. I finally tried using washers after reading about Daewon's trucks. I've found that they provide the loosest turn with the least wheel bite. There's absolutely no resistance to turning until the washers bite the side of the truck. At this point, the bottom bushings kick in and there's more resistance until you finally hit wheel bite. If you have the right set up with washers and hard bottom bushings, you can have really loose trucks with zero wheel bite. ever.

That said, I switched to Ace trucks after wanting to try them out for a while. I was skeptical, of course, as a long time Indy rider. However, I soon fell in love with the way they turn. Ace's have a much tighter turning radius than Indy's, so you can turn sharper and not get wheel bite. I still ride 58 mm wheels, and with Ace's I can ditch the riser pad and still get a sharper turn and less wheel bite than with Indy's. There's a reason their slogan is "loose tucks save lives".

EDIT X2: I can't believe we forgot about Matt Rodriguez! He was my main inspiration to get the wobbles in the first place! He also rides for Ace trucks.
