A great lure wont make a beginner trapper a rock star but a really great lure will make a noticable difference in the hands of a skilled trapper.
In bold is equivalent to a ford chevy argument or a new balance / asics battle. Both could arguably be "great, greater or greatest" all matter of opinion based on results for the
individual using the product, not because someone else says so. At the end of the day if the animal isn't interested in whats being offered, you aren't going to get that animal to commit off an odor. Just take a look at all the pages on forums filled with "what is the best bait for X" even though some of the folks posting have gone through many of the "great bait /lure" names out there aka "really great" etc and still in forums asking for the best. Lots of them folks have animals walking within a couple of feet and walking right by the "great" bait and lure without skipping a beat.
Simple or complicated I dont really care but I know there are a lot of mediocre lures and baits out there and I know there are some formulations that set themselves apart.
When a super trapper can't produce on a "great" bait or lure what is the problem? I don't buy into the "great" or any other fancy names for it. One will find them self circling the rabbit hole sooner rather than later with that mentality.
