Despite the bowl shapes not being perfect (a bit too fat, probably needing a bit more taper at the top of the bowl and perhaps a bit more meat in the transition between the shank and the bowl - I'm not great at shapes in PhotoShop), these all should be generally technically correct in terms of proportions and general shape: stem and stummel are the same length, bowl width is ~2x the thickness of the shank, bowl height is just over 3x the shank thickness, chamber to airway angle is 93 degrees.
These are all identical with one change - proportionally equivalent to a difference of 1/16" (which in this example would mean a 3/4" chamber, 2" tall bowl, and 6" overall length). To my eye the four silhouettes below present fairly substantial differences in terms of aesthetic appeal, profile, and general stance.

I'd be eager to hear which of these silhouettes people think looks the most right/appealing - I know for sure which is my favorite. If this gets any discussion going, I'll explain exactly what I changed on each of these (though I'm sure it's pretty obvious to a lot of you). As I'm starting to plan my 3rd billiard, this is something I'll be paying attention to for sure - just another example of minor details making a big difference.
