Just getting started but trying not to waste any money. I'm looking at K&M mic stands. Should I be going for a fixed or telescopic boom? Shorter stand and longer boom or the other way round? I will generally be recording either a standing singer or a seated speaker. The specifications of the models I'm considering are as follows: 210/2 Stand: 900-1605mm Boom: 840mm Weight: 3.2kg 210/9 Stand: 900-1605mm Boom: 460-770mm Weight: 3.2kg 210/6 Stand: 925-1630mm Boom: 805mm Weight: 3.0kg 210/8 Stand: 925-1630mm Boom: 425-725mm Weight: 3.0kg Any advice on the pros and cons would be welcome.
