RE: Which is tougher?
1. I do both
2. both are not hard to kill a deer. Depending on your area such as terrain, how the deer use it, limits you place on yourself, ethics, length of hunting season, how pressured the deer are, what you put it to the hunt and what you expect to get out of a hunt all depends on the hunter and where he lives. Which is more challenging?? Safe to say for me it is both as I enjoy both and also like other methods of hunting as each require a different approach to get the most out of it.
