Remember that rafts function much different than I kayak, which I am sure you know. As mentioned in an earlier thread you can not make last min adjustments in a raft like you can in a kayak. Keep you oars in the water when possible, this way you can make quick minor adjustments when needed. Remember: with oares you back stroke is your strongest stroke.
Also, your lines in a kayak are often different than you lines in a raft. You can't sneak that big ole boat in places you can get your kayak.
Rocks are often you bigest challenge in Brown's because with oras and a raft you are so wide. At the current flows a lot of the rocks are covered. Canyon Door and Pinball are read and run, pretty straight forward. Zume in a oar frame just requires a slight rightward movement through the rapid to avoid the rock/hole that comes in 2/3 you way through it. Fortunately in a raft the water wants to move you that way with with the correct approach. You said you know your line so Widow Maker and Rafter ripper are straighforward too. I have seen Raft Ripper give many an inflatable a rough time cuz the rock is harder to spot at 2k.
If you are up for a good challenge take you at Stone brindge but I recommend scoutting Sidels. The left to right move especially with paddle assist should be no problem. Twin Falls below that is an awesome wave train that really gives newbies a ride.
Enjoy. I will be out there this weekend too so when you see two girls in a shredder wave to us.
oh and one last thought, although we all know there will be a ton of people out there on Brown's this weekend do not rely on others to get you out of a jam. Give your newbies a good safety speach, teach them how to use the safety gear, express the importance of self rescue and more importantly... stay in the boat!
