Apart from being hugely lame (ever tried shooting from your other hand using one?) you cant screw a 4.5k bottle straight into it. for a start it won't fit but if it did you'd be picking little bits of steel braiding out of various bits of you for weeks. you will need a bottle and reg combo before the remote hose for it to work. preset ones are the best idea for that kind of set up because they will screw straight into it and just work
