It all depends on the antelope in the area,like say Wyoming some parts a 14 in buck is considered a dink but in others it might be average and in another a trophy.
For me I wan' t mass and dagers and then length.My first antelope was 14 1/2 and the next ones were,14 3/4,14 3/4,15 and 16 1/2.
My 15 in. buck out scored my 16 1/2 cause it had more mass.

I would think a 14 1/2 buck or longer would be a good buck for alot of pepole.

I have another tag this year and I' m looking at one that is around 15 in. and mass but the reason I wan' t him is because he is wide,his horns almost lay flat on his head.
It is mostly up to the shooter.Hope this helps BBJ
