Once again I find myself somehow compelled to write a review about a product, I had my own music store for many years before I retired so I feel (and hope) that my opinion might be of value to people needing help in deciding what to buy. I was considering buying the heavy steel wind up Stands that I sometimes borrow from my friend but decided to look again. After pouring over the Thomann catalogue I came across the LST-310 Pros, they were lighter and smaller than most others but could handle a load of 30 KG, the only downside being as I like to use my own lighting bars the pole diameter at the top of 28 MM but don't forget they come with their own bars, I ordered them anyway deciding that I could always make an adaptor. When they arrived I was surprized at just how light and compact they were, Ideal for the kind of work I do these days ( bars and restaurants) I put my standard sized fixing (35mm ?) lighting bars on them and was pleased to find that with the fixing screw tightened up there was no need for an adaptor. The one thing that impresses me is that the main joint for the central pole and legs is metal not plastic, in fact magnesium which contributes to the lightness. I am beginning to compromise a little on equipment these days but don't feel that these stands are a compromise at all as they are light, strong and do the job of heavier more expensive stands as they extend to the full 3m.
