Taking someone on hard whitewater without a roll
Hi everyone, I have a quick question. I paddle an OC-1, and I grew up paddling for years on class 4/5 whitewater without knowing how to properly roll. Of course, the day eventually came along where I really needed to learn, so I spent an intensive weekend geting it down, and have been working on it ever since (I am now very confident in my roll). So my question is... I have a friend who also paddles an OC-1 who I paddle with on a semi-frequent basis. He is a good deal less advanced then me, and does not have a roll. However, he is still a solid class 4 boater. He asked me to take him down the Lower G the weekend after next; do you all think that this would be a bad idea? I know that he has the skills to handle the river, and he can probably make it down every rapid without problem. However, if he does flip, he is 100% surely swimming. I know every nook and cranny on that river and can inform him of every hazard, but do you all still think that it would be a somehwat bad idea?
