I have been on range in October (my friends OIL)and March(my hunt) I didn't notice a difference In the animals behavior. They were really spooky on both hunts. I don't think you can go wrong with either the stallion or Rhodes. We went unguided and both killed oryx. I wouldn't go guided but...
My dad deer hunted that unit the last 2 years and saw rams both times. Let me talk to him tonight and see if I can get you some more info. Send me a pm with your email or phone number and I will get in touch with you.
