The good starting from the top:
a. Tama's QC8 quick set cymbal mate is brilliant. Replacing a traditional wing nut, the QC8 is a spring loaded holder that you simply pinch into position with two fingers where the wing nut would normally go. On or off in less than a second, and no wing nuts flying off over the stage when you're packing up!
b. Quick Set Tilter - instead of the top angle being adjustable and held in position by toothed gears, the quick set filter uses the friction of a set of metal disks to allow the smallest adjustment, and a more reliable hold that won't vibrate loose. c. The cymbal bottom supports the cymbals and felts and includes a sleeve to stop your cymbals keyholing. AND if it starts to wear out, it's reversible. d. Boom arm has markings to assist with set up position, and can convert into a straight stand by simply retracting into the top sheath of the stand. e. Adjusting the boom angle or length are done independently of each other. f. Plastic inner sleeves ensure a rock steady grip to all height adjustable parts. g. Double braced legs can be adjusted from a really narrow foot print to a really wide one dependant on your needs. h. All the above gives the quickest set up and break down I've ever know! The bad: This kind of quality comes at a price - WEIGHT - but at least you can cancel your gym membership!!
I always keep some tama cymbal and drum stands around just in case I want to add to someone's kit. The ones I have are super sturdy and easy to adjust. I think mine were made in the 90s. If there are better drum stands for this kind of money I am unaware of what they are.
