Just got off the river last weekend, we floated A&B. Red Creek isn't a problem, just go down the middle, no reason to scout.
We stayed at Big Pine, great site. It took less than 2 hours from the dam to Big Pine at 9k flow. The bridge only has about 1-2 feet of clearance right now below Indian Crossing. There was a party who launched at Little Hole and were going all the way to Lake Powell, they had to portage the bridge. You can get a shuttle company to help you with the portage from Indian Crossing take out to just past the bridge.
From Big Pine to Indian Crossing take out it took us 1 hour 15 minutes not touching the oars. The bugs are getting awful at the take out and none existent in the canyon.
