In an unmodulated test track you cant hear it. Therefore it isnt a problem. This could be measured. I have also used a wow and flutter meter on the brinkmann and the results were at the limits of the measurement ability of the meter - and way lower than any suspended deck.

I am not having a dig I am just saying why I hesitated to post the link and why I want the mod to say its ok. Its a very long thread for a start I am not going to cut and paste it all out. I have removed the specific reference from my reason to avoid hassle. Please amend your post to do so also.
