Yea i bought a pure freedom trolley of the world famous wagga, never got on with it. Bought a couple of backpacks and gave it a good go for a couple of years. I can see where it could work well but it didnt suit most of my rounds. Im very quick and fit so when i took refilling and van moves in to account i was no faster on majority of my rounds. Although i was safer i didnt think all the hastle was worth it. Maybe when i get older(im 37) and less mobile i might give it another go, but im happy trad for now.
