See less and less new FB being bought by my friends and acquaintances, and more and more used FB for sale now that there are quality windsock options out there, and that market will only get better whenever Skyfly gets around to releasing their mallards.
Around here in eastern SD, the guys that are running 10 dozen plus FB mallards are either using GHG or Hardcore. Guys who have 1-4 dozen seem to have more dakota and AvianX.
We run a 10-12 dozen mix of windsocks and hardcore rugged series fb.
