Personally i used to use Vert feed for my air tank all the time and i jsut recently designed and made my own drop forward and i love it so much. SO much easier to Aim and it balances the gun out so much. evry time i see someone with a botle off back of handle streight out back i think damn that thing must be uncomfertable. mind you i like to aim too not jsut spray and pray.
thats my drop.
