I first came across that vid about a year ago.
I have never seen the products up close though.
The edges and hoops apear to work well on the video.
I can see how the edge inserts would be useful to a drummer with a beat up kit.
When you think about it the edges aren't much different than a reinforcement ring.
The composite hoop looks really interesting.
I think the bearing edge inserts are quite a good idea for those who want to switch over the character of their drums whilst maintaining only 1 drum or set. My issue with these is the sonic affect. In our extensive A-B testing of separate bearing edge designs, we found that a separate edge, no matter how well interfaced, significantly reduced shell resonance & ultimately excitement of the reso head. That affect was most prominent on all stave shells (due to the conduit affect of unmolested vertical grain) and other shell forms where the shell was medium to thin in thickness. Conversely, on a thick ply shell, these separate edges could work quite well, as such a shell contributes little by way of resonance.
I think the composite hoop has more merit. I especially like the different edge heights to enable hand playing & strong cross stick click. That said, such hoops do not contribute much in the way of tone in the resolved sound. They're quite similar to thick ply hoops in that respect. To me, they sounded muted, as opposed to "woody".
The snare drum in the sound clip was as dead as a dodo. My best guess is this was partly to do with non resonant hoop mass, those separate bearing edges, & what seems to be use of the internal damper.
Overall = not for me, but for those who want a dry sound, I suppose both products have their place. Best bit = the low & raised sections of the hoop. Me likey that!
As KIS said,
Slight lack of resonance is the first thing that I thought of when I looked at the product videos.
I couldn't see myself ordering a new shell and not having edges cut so that I could install edges.
I would perhaps install the edges and the hoop on a snare drum that I don't care for that much. It would become a side drum or the like.
Recutting bearing edges is not that hard to do yourself and it isn't that expensive to have it done.
If a drum isn't worth having the edges recut then it probably isn't worth buying the inserts either.
