I think there is a group of people going to Deckers on sunday from "Colorado Kayakers"
Check out the group and join were doing trips all the time...
The Deckers run is mostly 2+/-3 due to the amount of maneuvring around all the rocks in the river with no huge major rapids, the only big slide/drop is the Chutes and its a 3+/4 depending on the flow but it has a nice pool at the bottom kind of like Union Chutes does, you can tell the Chutes by the big NO TRESSPASSING signs everywhere to keep swimmers and tubers out.
There are lots of PI/TO choices all up and down the road, my favorite place is the 2 miles upstream of the Chutes.
There is a section that flows thru a fishing camp that has barbwire across the river even though its legal to float thru most people start their runs below it to avoid any hassles.
My advice is the next time your out there while he is flyfishing take the car and road scout from Deckers town down to the confluence of the North Fork and the S. platte where the Waterton Canyon run starts, you'll find something fun to run!!!
