Going to COSept. 14-24 for my first elk archery hunt in unit 77/78 for a cow elk, OTC tag.

I was planning on just paying $250 for a cow tag. Being a lifetime whitetail hunter I just assumed getting my tag on a cow would be easier than a bull, just like a doe is easier than a buck. After reading more and more, should I pay the money for an either sex tag instead?? I know fate says if I only have a cow tag, I WILL have a bull at 20 yards, butwhat I am getting at is atthis time of year, would a bull actually be easier to hunt than a cow? Are they easier to call in and locate? I'm an elk novice, what should I do here? I'm not overly picky on rack size
