I never carried so much in the front with my Hoppediz, my son was already one and a half when I bought it. But I think the "chaka chaka hold" is very smart, especially since the Hoppediz is so stretchy, you need to pull harder on that wrap than on other wraps. I didn´t really felt the need to do the "chaka chaka hold" with my Storchenwiege, it got tight anyhow.
I think the knot is good for the rucksack carry, but it takes time and I loose control over the wrap when I do it. I like the knot best when I make wrap cross carry on the back.
In my instruction of the rucksack carry (I have the German instruction book, I don´t know if it´s different), they have the wrap sort of rolled on top of the shoulders, instead of spreading it out, looks very uncomfortable to me.
I don´t like the classic Rucksack carry, the way you do it, my shoulders start to hurt immediately, I think it gives so much relief if your chest helps to support the weight, either if you have a knot or cross the wrap over your chest. If you want the baby high up, I think some kind of tibetan carry is the best, then you also get that help from your chest.
