Having used aluminum panniers with heavy mounts / frames and fixed capacity the light weight bag snake is a welcome change used with dry bags. I can attach bags larger than my former panniers or go with smaller bags for shorter trips, either way the lower weight is noticed right away, your rear suspension will thank you.
GCAG has been a real game changer for my honda xr650l. It has cut my pack up time tremendously they never come loose and keep my center of gravity low and close. Top end product
So the bag snake system did very well for me out in the wild. Easy to strap down and easy to undo(except if you have wet straps that cake mud and then dry in the double d-ring). I would consider using these in multiple ways on any bike. You are only limited by your attachment points really.
At first I couldn't understand why these were sold for one bag at a time and not in pairs. Then I took my DRZ400 out while not needing more than a tool bag and a jacket. I simply strapped my dry bag to the Scramble Rack as a tail bag using one Bag Snake Kit. It worked great. Now I understand. A quality, well-designed product is a beautiful thing.
The bag snake kit is by far the best method I've ever used to tie down a bag on my bike. I used it last week to tie down a 50L Wolfman bag.After over 100 miles of dirt roads, the bag hadn't shifted at all.
