wait...
"fuzzbuster?" really? How old are you?
i am 41 and i barely remember that term for a rd (my uncle had an actual "fuzzbuster" in his car)
and as far as mounts go -- the bel sti is one of the heaviest rds out there. It works on the blendmount just fine. Actually, its weight is one of the reasons i bought the blendmount. Suction cups will fail, often within minutes in hot and cold temps. I was tired of picking my rd off the floor or trying to catch it while driving.
The rd unhooks from the blendmount in seconds, allowing me to store it out of sight whenever i park in a public place/in the sun.
I have a visor clip mount from escort also and it limits the sensor's "visibility" whereas the blendmount gives both front and rear sensors the best possible clearance. Not to mention a visor mount eliminates the use of the visor for its intended purpose, which i need since i am often driving to/from work at both sunrise and sunset.
As they say in the laser jammer business, "stealth the car, not the install."
