You lost 3 fps compared to what rest? Drop away? Just wondering. The only time I really chronographed speed differences with rests, I was trying out a GKF Whisper Disk, which lost 3 fps (compared to a TM Hunter) when the vanes were aligned (as well as I could) with the slots, and only 6 fps when I rotated the nock so the vanes pretty much slammed into the foam. That day, I reinstalled the WB that had been on the bow, and speed was within 1 fps of the TM.

I also have heard there were issues with the year 1 360, and those top 2 containment fins. I was wondering if the '06 version was better. Thanks.
