Hey, I too downloaded the demo of pinwheel's "OnTarget2". That is a cool program! They don't have my 2006 Reflex Highlander (obviously), so I used a 2005 Reflex Grizzly, then changed the ATA to 36". I entered in all my setup info and just let the program do its thing. Here is what it displayed for me:

CURRENT SETUP:
2006 Reflex Highlander (IBO: 305 fps)
67# draw, 29" draw length, 75% letoff
Beman ICS Hunter 340's @ 29" cutlength (Vanes)
100 grain tips
(peep, string loop, nock, silencers, etc...)
Spine chart marker is right there on "Good"
272 fps, 10.17% FOC, 69.20 K/E
