Avery- If this is the first time you're creating a strike weight continuity, all of the shank weight shortcuts may be obscuring the basic issues. You need to have the "raw" measurements and you need to have an ideal strikeweight curve with gram values. Shuffling the shanks by weight will save you a little extra lead or sanding, but you can do a fine job just by gluing them up as usual, weighing them, creating a curve and adjusting the strikeweights. It might be better to take the simple approach first time.
