Seems as though every bow I build the bottom limb seems lighter. I can flip the bow and the full draw still looks the same. I have glass bows that look the same way when at full draw. I guess it must be the way I draw the bow. I shoot three under and place my drawing fingers about where they would be with or without the arrow there. You can see it on this little kids bow also. I seem to be able to shoot fairly well. Whatta you guys think. Paul<><

Looks ok to me. Three under will draw the lower limb more.
I don't know, maybe it's just an optical illusion since your bow are is a little closer to the bottom limb in the picture.
Just thought of something you could try...
Put the bow on a tiller stick and draw is some amount. Lay it on a big piece of paper or something else you can draw on. Trace the profile of one of the limbs. Flip it over, making sure the center of the bow and riser are positioned the same and trace the other limb. This should show you any deviation between the limbs.
