What I like about the Glidetrack is that it allows me to walk around with a fairly portable set-up and grab dolly style shots in places that just wouldn't be practical with a normal dolly and rails rig. When using the Glidetrack you suddenly find that your surroundings offer a lot more possibilities, walls, rails, steps, and even the odd wheelie bin have become camera supports in my work and each have provided shots that can give your films that pro look without splashing out on a full dolly rig.
