Jim,
Can't move to the slide, it's a sims teflon. Came on the bow.

BGfisher,
I have the hush kit, string loop, and a true peep on the string. I think I got the readings I did because the chrono requires the arrow length to be put in on the front of it. I measured the arrow like you normally would, valley of the the nock to the end of the insert, omitting the tail of the nock and the point length. I was back at the shop and asked if that was correct. He said no, it is the total arrow length. He said by not putting in the entire length, I am probably 10 FPS or so slow, this would be about where I thought it is shooting, mid to upper 280's. These arrows are pretty light at 390 gr. I plan on increasing them to the 420-430 gr. range for hunting, which will slow me down some.
