Well I was looking for a good way to rig my kayak for the hike in. I think I've found it. I rigged the whole thing with the shoulder straps from my Gregory Denali Pro pack and an old hip belt I had from the last time I went into Jarvis Creek. I went to AMH and bought 5' of 2" webbing, 5' of 1" webbing, two dual locking buckles, two 2" sliders, and two 1" sliders to rig the shoulder straps with. I'm not sure what the whole set up weighs but it seems to carry fairly well (but what does a few straps matter when you are already carrying 44+lbs of kayak and gear?). So far running around my place with it on, it feels more comfortable than the set up I had going into Disappointment Creek. I'll have to let you know how it works after the weekend. Here's a little video I made with the set up.
Here is one of the last runs done on Jarvis Creek. (It doesn't get done all that often due to the level of boaters in the area, accessibility, and knowledge of the run).
