In glassed, Hill style longbows, that are custom for your draw: is one, cut to the length using the formula of 60" plus the last digit of your draw, ie; 28" draw=68" bow, still a better choice or with the glass bows does one step down 2" in length because of the glass? I understand this may bump up speed a whopping 4fps or so, but, do you give up too much stability for it? I understand f.glass changes some of the requirements.
Now for the short version, is a 66" custom Straight Limb/Slight S.Follow too short for a 28" draw? Or is 68" the "only way to let it fly."?
