"AMAZING Sound difference! 
Most manufacturers of drums suffer from floor tom leg design and the drums don't sustain.  
I'm currently out Tech-ing for Josh Baker and both of us can't believe how much the Flex-Tips improved the sound."

​-Jerry Johnson, Drum Tech (David Byrne, Dave Mathews Band)

Flex Tips floor tom leg isolators
While our Dynamount™ Floor Tom System is ideal for drums with un-drilled shells and does away with shell mounting, Flex Tips™ offer an effective resonance solution for floor toms with legs already mounted to the shell. They are sold in one size for  Standard floor tom leg diameters 3/8" (9.52mm) to 7/16" (11.10mm). Simply remove the rubber ends currently on your floor tom legs and secure FlexTips with the provided allen wrench, making sure the leg is centered in the Flex Tip™ collar. 
Flex Tips floor tom leg insertion
The leg of the floor tom inserts part of the way down into the low harmonic frequency spring. This separates the leg from the floor, keeping resonance from transferring into the floor. By moving your leg various distances from the floor within the spring, you can often customize the amount of resonance, or decay, in your drum. Closer to the floor for quicker decay, farther from the floor for longer sustain. Experimentation with your drum is recommended to balance the sound with the rest of your set.  (It's not necessary to remove the rubber end of the Flex Tips™. The picture is for illustration purposes.)

Before purchasing, you can test your floor tom to see what kind of resonance loss is occurring within your drum. Simply have someone pick the drum up off the floor and play it while it is being held. Then set it back down, and listen for the difference. Try placing the drum on different surfaces (carpet vs. concrete, etc) to see how this changes the resonance.
