Two things i noted:
1. Short fades put alot of stress at the riser/ limb junction, so make the limbs bend more toward mid limb or tips and less at the fades. If you look at the riser drawing that Binghams sells, they do look short and fat, but that is the cut out shape and require you to sand the fade down. A good guideline is paper thin at the end of the fade tapering smoothly to 1/16" thick at 1", 1/8" at 2" and 1/4" at 2" or 3".
2. If you see a problem with the bend of the limbs DO NOT bend it further. Fix it first. Also, when tillering, never draw the bow further than your draw length or desired draw weight. For example, If you want 50lb at 28" and you hit 50lb at 12", obviously its too heavy and the limbs need to be lightened up. Its usually better to thin the width or length of the limb than the thickness to change tiller in fibreglass bows. You can do this by narrowing the whole limb or by trapping the back. Sanding the fibre glass,should be approached the way you would approach drinking whiskey: Do so in moderation!
