I make all of my bows with a shorter lower limb for the same reasons. It balances the bow in the hand while carrying, and goes a long way toward putting the static and dynamic fulcrums in very close proximity to one another... better aligned with the string fulcrum too. This minimizes the shift from static to dynamic that can be quite sizeable in some bows. How these things are oriented in a bow influence how it draws, shoots, tunes, etc.
