I'd go with the lowest cost option
A) If you make a mistake during construction it wont cost too much
B) If you make a mistake with the design it wont cost too much
C) In a couple of years you may want to adapt the design or you may feel the construction is a little heavy or not stiff enough etc you haven't wasted too much money on your hulls
D) If it gets totaled due to a collision again you wont have wasted your money.
If it works first time and you have a fast F16 then you could always make another using more exotic materials.
In the mean time keep us informed on your decision
