So I am getting ready to order my 1st pair of courteney boots after doing plenty of research. I am stuck between the selous and safari model and also the ripple or Tyre tread. I'll be using these for africa as well as south texas nilgai and colorado mule deer hunts. What are the pros and cons and which boots would you suggest? I typically wear a size 12 or 12.5 in my other boots and shoes if that makes a difference
