At that level you definitely want to stay out of little niagra on the right side of big drop two. There is a long pool between big drop one and two from which to scout. You can also land on the right side above big drop three, or you can simply run it right of center. You do not want to be on the left side of BD3. Frog hole down in satan's gut (big drop 3) is more like a giant forceful breaking wave than a hole at that level; nothing really to worry about punching it (it's off the right side of the center tongue). The above mentioned "North Sea" is actually mile long rapids, and is a phenomenon that forms only at 50,000 cfs and above. Below that flow the mile long rapids retain their individuality. Look out for capsize rapid, it's got a boat eating hole after the river bends right that is hard to see until you're in it, without a scout first. Hope you've got a motor for the calm before and after the rapids. Also, aside from Dark Canyon, which is definitely a must see, you should hike up to Doll's house out of Spanish bottom. It's got a granary up there, and the terrain is spectacular. It's an awesome trip, have a great time, and try not to swim above big drop 1.
