1st - it is all flow dependent. Lower @ 900 is easier than Kermits @ 600.
Dumonts is mostly pool drop ledge holes. Dan has hit this run a 100 times & if you go with someone who knows it - Definitely takes some of the punch out. @ 600 this is a easier than Lower @ 900 or Kermits @ 600.
Alto-Alto has some willows, potential for wood & a couple of big holes above 600, but for the moves are fairly easy. More of a wilderness feel. I still feel at the current level of 450 it is the easiest of the bunch.
I have run both Kermits & Lower in the last week. Lower is definitely harder at these levels. But - if you walk elbow & 1/4 mile, Lower is easier. Still some good stuff & get to know the river. If you punch thru Elbow & nail 1/4 you will definitely feel confident in running some stuff.
I have had at least 3 friends that have pretty much quit boating after swimming at 1/4 mile.
While, I think there is something to be said about having your own crew and running things the first time with "fresh eyes". There are a bunch of us that are willing and would have fun showing new class 4 boaters the lines on these & many of the other Front range class 4 runs as they continue to come up.
As long as you have a completely solid roll and have either been progressing through the Poudre & the Arkansas, or hitting the playpark 3 times a week. PM Vince or myself & we will try to get you out there with us as we are going.
There is great opportunity to boat a lot, meet new people and see old friend in the next couple of months
