Did you try the delayed deactivation Luminara suggested, fsuman? I do find myself accidentally deactivating the saber quite often and was wondering if the delay helped.
Nope, not yet. I used it for Halloween, but I changed my grip on it so that I wasn't accidentally turning it off and on. But I still plan on adjusting it.
Have you changed any of the other settings? I have found that the default settings as far as swing sensitivity are perfect for me. I never get phantom swing noises because the sensitivity is too high, but I also don't have to swing very hard to get the sounds to register. It must be a fine balance, but it's really been super tight. I wonder if that's because of the CSv4? I had to mess with the settings on my Flex quite a bit to get them to my liking.
