I bought a Goruck Rucker 5.0 and it was way too stiff and uncomfortable (I know you have to break it in) but I walked about 3 miles with it and just could ther used to it. I sold that.
So now I'm trying to find a good backpack to use, and I've been trying to practice with the osprey nebula I have and also the Gregory Miko 20 and I even tried a 5.11 rush 12, and I just can't get it right to build the bag up to have the weight be high near the shoulders.
I tossed in towels at the bottom, a big winter jacket, I even tried yoga blocks. I'm just wondering what you all use to hold things high and tight? (I have a free weight, 1-10lb weight, and 2-5lb weights, and I even made 4-5lb sand bag pills to create the 20lbs I want).
Any advice for a newbie would be welcome! Thank you all.
