Thank you, Lentamentalisk.
Voile straps arrive today, so thanks for the tip.
Roger that regarding the unpleasantness of the weight on the front end.
Will only use the large bottles when I’ve got one of my kids with me (need to carry water for two) and there’s no known water access on an overnighter.
Thanks again!

Is this okay (diameter of bottle larger than diameter of cargo cage), or is it a recipe for disaster?
