I was on bridges at little over 4 with a group of newer paddlers. Everything went really well. It does feel bigger but most of the rapids are straight forward. Greyrock is easiest staying right and then working left. The S turn above killer bridge is easy to make, and then the rapid itself you can run mostly center. Roller coaster is big wave train that you can skirt most of and a big eddy still above red house hole. There is a sneak on Red House depending on the level far right and should be in which is the only hole that can ruffle your feathers a bit.....
Depending on your girlfriend and her experience with run off I would bet it would be a blast for yall. The paddlers really liked the run once done, but while in it were extremely focused on getting down due to the bigger water
