I really don't know what the answers are for ratings. I don't think that the V grade can continue to be rated as difficulty only. It is not possible to rate rapids based soley on how difficult it is to run them. Run them.... correctly, survive them, hit the intended line, run an unintended line that turns out great, upside down, swim, etc??? We are fortunate to live in the media age as a large portion of this discussion is really mute. A large part of being a solid class V kayaker is having sound judgement as well. I think it is important to keep the "judgement" word in all discussions as when it is all said and done this is what gets you home at the end of the day most of the time. I mean how does one compare Jacobs Ladder and Gorilla, Paralyzer and Coyote Falls, Tomko and Palouse, etc. All V's but obviously very, very different. There is only one way....you stand at the top of it, look at it, assess your day/skills and choose wisely, period. If I go out west or to another country and I am going paddling on Class V, I WILL get all info that is possible and of course scout. This is all we really can control and if you find yourself on a class V somewhere with class III skills than it is most likely a poor choice and huge mistake. The Green, love it! Ratings, I believe anyone with solid class IV skills can competently run the Green with very little difficulty. It is a great river to hone your skills on. You get congested boulder rapids, big bedrock rapids and slides on the Green. Perfect example of ratings; Power Slide and Rapid Transit?? I mean they are not that difficult! But if you mess 'em up and lots do, than they hurt bad?? Do they take class V skills?? I really don't know.
*as far as the Green Page is concerned, I am willing to help if I can, but whether Frankenstein, Boof, or Chief is class V is so subjective and again so mute that I really don't have much to offer and I think the page rocks already. I think class V should just be the "get out and look at it" class:)
