That all makes sense; with regard to the Goblet Squats, when the load starts to increase it does have a tendency to pull on the upper back so a strain is very possible.
If you don't have access to a barbell, have you considered doing ordinary dumbbell squats with the weights to the side, that's one way to get around the pull on the upperback with the Goblet Squat variation; alternatively, the upperback needs some work as well. It may evenwork if you do less reps per set which means the upperback won't be under the strain for as long each time before you can relax it, that may be workable.
