Haisen. I've hunted 43 and 55 recently - simply put, the Gunnison Basin herds are struggling. Before the recent harsh winters, 43 was a great sleeper tag that was always undersubscribed, but still held some great deer. However, the unit has been both discovered as a overlooked unit and the deer herd has been hit by several harsh winters making it a tough go. There is always potential there for a great buck, but I would say there are much better units in Colorado right now to kill nice bucks. I hate to be a downer, but I have also hunted 75/751 in the past 4 years and it is not nearly as good a draw as it once was. IMO deer numbers are also down, in fact last year they cut tags in the area. Again, there is potential for nice deer as there is in a lot of places on the west slope, but IMO there are still better units than 75/751. Good luck with the search!
