Sock It To Me lines.
Agreed- it is difficult to scout Sock in a raft. There are basically three lines to get through the rapid, with a 4th alternate if you take speed into consideration.
1) enter left to right. largest hit in the rapid. go straight into the catchers mit, squaring up straight down the gut.
1a) hit it at normal to quicker speed- most fun, but is also the most likely to send you into the magnetic wall on the left. If you're getting washed towards it you can race it and try to pull the boat to the middle of the river, but if you hit the wall you'll pin since the raft will be dead sideways to it. Or, if you're going towards the wall you can straighten the boat up to address the wall, possibly bouncing off the wall which will either send you into the eddy on the left upstream of the magentic wall, which is called 'the closet. It could also push you off the wall back into the main current.
1b) do the same line, but be pulling up stream to slow the entry into the rapid. When you hit the wave you'll stall out, typically filling the raft with lots of water, then get kicked left into the closet. Since you'll be going so slow, the magnetic wall won't even get near the boat.
2) run from right to left, hitting the meat. slightly smaller hit than option 1, and keeps you more in the main current- do an upstream ferry towards the right and the magnetic wall isn't an issue.
3) sneak- far right, whole way down.
