Rob,
In case you didn't know, when you swap out a factory set binary cam bow shipped with the smooth mods to the fast mods the let-off and valley settings don't always follow along exactly in the change.
If you change from the smooth to the fast and the valley dissapears and it feels like it's less than 80% and wants to go chances are you need to make a small adjustment on the stop peg.
Very small moves to the high side of your top cam with the stop peg can get you right back to a comfy valley and let-off.
If you have an accurate scale you can figure your peak weight and holding weight and do the math to set your let-off.
When I mean a small move I mean small too........my Tribute losses valley and let-off when I swap mods but about a 1/16" move of the stop peg brings it right back.
That's the beauty of the design, you can fine tune your personal feel.

I know you're an experienced shooter and a short valley wouldn't be a factor but the adjustment is there if you need it.

Congrats on the bow, it will come in smoking at 28.5"/ 70# /350gr and fast mods.......I'd guess in the 3teens?

Call me anytime.

Oh and when you set it up to paper tune......nock dead level, and midpoint of the shaft split the berger holes evenly.
I justset-upmy 2nd 2006 model for paper tuning and they just keep tuning perfectly this way.........everything as level as you can get it to start.
I had beautiful bullet holes in about 6 shots with minor rest fine tuning for launcher height.
