Eric, you have a good eye. I measured tiller, shot the bow about 70 times, 90% with the bottom limb up. Measured again & the results are the top limb measures at 7 5/16, the bottom 7 7/16 for about 1/8'' difference. Before shooting today the difference was the same. Looks like I'm going to flip the grip, shoot some more, and re-check limbs with gizmo etc. I have weight to spare if needed but I really like how it shoots now so I may not scrape the limbs if the gizmo is pretty close. The bow now has roughly 250 shots taken and shoots quite nicely.
