Using Sliders

Sliders (or overkeepers) have their place, although, like Azurgrip, I tend to prefer to hold overs myself ("overkeeper?, I AM the overkeeper.") My sentiments exactly. Sometimes they do come in handy especially for confined spaces. I often will help the operator use one and apply tension by sliding my thumb along the bottom of the slider and the top of the rail. I can help him hit exact marks in this way. As a financial necessity and because every job has one now, I've acquired a few in different lengths (with a partner) that I can bring with me. I have a 6', 4', 3' and a 2'. (We basically bought a company that had them). They also come in handy for shots when a lateral move is needed during a move and you are on track. I have overcome a little of my reluctance to use them and see them as just another tool for camera movement which has it's place. They can save you if used in the right way. They can also be a nuisance if you're working with a director or DP who doesn't really understand what a dolly grip does. They can be unweildy, and tend to sag at one end or the other as the camera moves, making it necessary to support the ends. The main thing I'm trying to get across is, don't forget you have it as an option when you have a tricky move. It can save you if you know how and when to use it.
