Ditto on the speed loss issue. There is some but whether or not it is significant depends on your perspective towards speed. I do not have exact figures at this time though I plan on changing that this weekend. However, just using a 10 fps figure as a reference...to some that 10 fps might seem significant if they spent much of their time and resources trying to wriggle every ounce of speed out of their setup that they can. On the other hand, I am sure there are folks that do not feel 10 fps is much to loose at all for the benefits that the Whisker Biscuit offers.

On a side note, I am really surprised to hear the above comment about noise...I thought it was relatively quiet.
