Really? I didn't realize that! Well, in that case, what I would do, as long as the holes are the same, is use the later model ones that have the bolt with the hole through it, for working gigs, but keep the original ones off to the side for when (if) the day comes that you should ever want to sell to a collector. I don't think the brackets are all that expensive are they? In any case, whatever is original to the drum should stay with it, in my opinion. But there's nothing wrong with taking advantage of improved technology for working situations -as long as there is no drill involved! In this instance, there wouldn't be.
In addition to that, I think the newest versions of the brackets are still retrofittable and they have memory lock ability! I have been thinking about trying one of those on my Downbeat bass drum for the cymbal mount.
