A-rigs and swimbaits

Hey there, I have been using some smaller Berkley and storm soft body swimbaits. Those with the hook sticking out the back. I can usually fish the bottom with those. When it comes down to hard bodied swimbaits that have trebles on the bottom, how does one fish those? I don't do much swimbait fishing and would like to start throwing some big ones. Maybe even an Arig. My question is, how do you fish these in deeper waters. I assume you wouldn't want to drag it on the bottom being that they could get snagged with the trebles, plus they're pretty expensive. How do you guys retrieve them and fish them. I really want to learn how to use them effectively and so any information you guys can provide me with I would really appreciate. Thanks...

Those are mainly fished in the upper water column or open water where you are less likely to get hung up
