Re: Balanced/Inbalanced field length
If you reduce the V1 to Vmcg at high weights you will probably not get off the ground! A balanced field means (if I have it right) that at V1 you can just stop or go and you will only have one V1. At a field that is longer (ie not balanced - I think the term "unbalanced" is incorrect) you may have a range of V1s but this will be shown as Vmcg 110, V1 125 130, Vr 137, V2 140, which means that your V1 range is between 125 and 130. Vmcg just tells you the min speed for keeping directional control.
