Yes, the Dixson is great. Simple and works well.
The Gibraltar is a complete P.O.S. in my experience. Been through two of them.
It will not stay on the hoop, the bolts that attach to the hoop will not stay on, AND they will destroy the hoop eventually. The vibration of the pedal/bass drum through the floor eventually loosens up everything. Stay away. The Gibraltar bass drum riser is the worst thing they make IMHO.
