Ordered this Optimount Holder to upgrade an old Sonor Force 2000 Tom. The old mounting system killed the sustain of my toms noticably. Now the sound is more what I want it to be. (Of course, more sustain doesn't always equal "better" sound. It always depends on what is required in a certain situation.)
Also, dividing the stress on the material (that results from mounting the drum) to four diferent points - two near the top, two near the bottom of the drum - seems to be a good idea.
Of course, the drum's freedom to move is not as big as with other systems that grab the hoops. But I think that is also more a pro than a con.
And I like the look of these holders.
They only match Pearl tom arms I think. But those are really good as well in my opinion. Try the TH900, good price and quality.
I have not yet tried the newer aluminum Optimounts but my guess would be these older steel ones work just as well and I will stick to these because of the price.
I can recommend the Optimount system.
