I would like to order a custom dominator but would like to adjust one parameter a little further, the tail width, outside of the adjustments allowed in the online software. The dimensions I am after are; 6'6" X 20.75" X 2.75", nose width 13.3" which all fits in the software but I would like to make the tail 15.2" but the min I can adjust it to is 15.44". Can it be done? cheers.
