Motor Mount ??? for 540 L/XL size motors

[longballlumber]

Does anyone have some input on using this style of motor mount without support on the rear; http://www.offshoreelectrics.com/pro...rod=tfl-502b12 vs. this style of motor mount with the motor supported on the end; http://www.offshoreelectrics.com/pro...jwr-mount-rail
My application will be using a 540 L/XL size motor. Do these size motors make enough vibration that the end bell of the motor needs to be supported?

unless the motor is for a stationary application...its a good idea to support both ends of the motor . I've been carving wood blocks for mine.
