How to Run the Main Channel Rapids at Medium Flow by Sam Gravel

 McCoys :

At the top there are 2 massive holes, Phil's and Sattler's. There's 3 main lines you could take to avoid these hazards. Either take the meat line through either Sattlers or Phils. Another option is to thread the needle, you can punch the end of Sattler's at the side and paddle hard to miss Phil's. Once the top section is complete you paddle straight down and follow the wave train.

The Lorne :

It's a simple rapid, you go straight down the large tongue in the middle of it and get hit by all the crashing off center waves. Once you reach the bottom there's multiple channels. Your best bet is the far right one which is just a large wave train.

Butcher's Knife : 

This rapid is mainly a large wave train that bends to the left. On the right wall there are very sharp rocks which are unpleasant to hit. To run this rapid you stay left of the central hole and away from the right shore. Follow the wave train down

Norman's: 

Norman's is a gorge-style wave train. There are a few holes on the right of it. Most of the rapid is a large diagonal wave train. To run it you start center-left, and drive right of center through boils.

Coliseum : 

Coliseum is usually the biggest rapid on the main with many features. Avoid the top left and right as there are many hazards such as : nasty pour overs, large holes, and rocks. In the middle-left there's a huge wave-hole called Big Kahuna. Many lines are possible. Either sneak left of the big Kahuna, punch it, or sneak right of it. Then follow the big wave train down and eddy out in either the right or left eddy.

Blacks :

Blacks is the final stretch before the take-out and just a simple wave train with a few hazardous rocks is at the bottom which divides it into 2 small channels. The smoothest liner is the right channel.
