The costs of being anal; But there is a practical reason for it...
I recently re-acquired a 600 Series DCS that I sold 14 or 15 years ago, I guess. I didn't realize how much had changed on the 600 series in that time. Most people wouldn't care, but I am a very detail oriented and practical person. In this case there were some legitimate things to sort out and one or two very trivial things.

Issues: The cymbal tilters on my older 600 series stand have M6 posts with the dual wing nut set up. TWO chances for me to lose something every time I take a cymbal off or put it on. The newer ones have M8 posts and the quick release things which I LOVE because whenever I am not playing my drums, the cymbals and snare drum are in their King Kong Kases. Really slows me down dealing with wing nuts.
The older stand doesn't have the memory lock on the tripod. Most people may not care, but I am meticulous and I like all my bases (2 in this case) set similarly so that whatever I grab can be immediately positioned properly. Everything has a memory lock setting and a specific place in the rig.
Next is the vertical tubes on each cymbal arm. Who decided that you need to be able to jack your cymbals 10 feet into the air? These aggrieve me because they extend down into the region where the wing nut for the base resides. It can be fussy to have all that extra tubage (I made it up, but this is MY story) in the way. So, I have the short pieces to replace them. The short pieces also modernize the memory locks which is certainly trivial, but I want everything updated, when possible.
Next up are the booms. Long, and potentially sticking out into traffic. I like the BA-TB's. I have one now and three on the way.

Not only does this give me flexibility to put things where I want them while keeping a really clean footprint, but when you add up all the changes, it really cuts weight to. When you load all the 600 series stuff into a case or bag, every pound you can eliminate helps!
That leaves one really trivial things. The last memory lock on the middle section of the stand. The original one is completely functional, but it drives me a little nuts to have one thing on the stand mismatched. HOPEFULLY Sam has one and can hook me up when he comes back from vacation.
So... does anyone share my quasi-irrational thinking about hardware?
