Groundhog, the best way to look at it is on how your work and round is and see what suits you best and what makes you your money quicker.
Like you said you tried a back pack and didnt like it so you changed in your situation for the better, just as i tried a vanmount and changed to make my life better.
I never said anything about all the lads on here that use vanmounts are wrong and should change, if they were unhappy then they would,its all horses for coarses i tried a trolley system first that was worse as my round has loads of steps so it proved to be of no use at all to me.
The trolley was sold to another wc off here and his work suits it to a t, things are only as good as the situation your using them in allows them to be.
