It ended up being pretty great. There wasn't many people out, so that was nice. I was taking my parents down, who had never been on a raft trip. My dad ended up staying in the IK through black rocks and was fine, he enjoyed it quite a bit. At the tight spot in black rocks there was a bit of a lateral wave on the right and a hard eddy line on the left, my boat was pushed around a bit and my left side tube was dunked a little, but that was the only part that was anything but relaxing. Thanks for all the advice!
