I did notice something there. Take some advice and get rid of the Ultranock. Get a loop tied on in it's place. I'm certain that is at least part of the vibration problem. And you'll maybe gain upwards of 10 fps in the process.

I see your arrow weight, but what is the peak weight of the bow and drawlength? You should not be exceeding 60# at any drawlength over about 28".

For anyone. You show me an old Polar LTD shooting 250fps and I'll show you someone living in LaLa land. I was around when they came out, actually owned one. They had trouble amking 190fps back then---like in the 70's.
