You're welcome Jerry.
When you say balanced, do you mean at equilibrium, or do you mean with VTF applied ?
If at equilibrium, is the counterweight at the end of its' rearward travel ? - you may be able to factor in some additional mass to the counterweight to enable you to move the counterweight nearer to the pivot point and thus lower the interia of the arm assembly and also lower the effective mass slightly.
In my experience the closer that weight is to the pivot point the better the situation is.

Yup, with vtf applied.
