People can complain about everything, but ultimately if you aren't willing to put in the work to freelance for ducks then you will struggle.
Making a reservation at an SWA does not guarantee anything, but you can have some serious epic hunts at SWAs that require a reservation. It takes time to learn these places. NEVER expect that you are going to have a good hunt on an SWA reservation until you know that SWA well and you can pick the correct spot AND hunt that spot correctly.
There are also miles upon miles and acres upon acres of other great duck hunting areas in Colorado. Get away from people and put miles on your truck. Maybe dont focus off 76, but there is also great hunting off 76 too.
It is all about conditions for ducks. I try to make sure I pick the days to hunt that will yield the best results. This means there will be a lot of birds in the area I hunt AND there is some sort of weather to assist in killing them. This also means calling in sick to hunt a week day if the conditions seem perfect. Many times my predictions are dead wrong, but I learn each time and sometimes I kill them.
If you want to do well on at the SWAs, stick to them and learn them. Refill a blind that you saw shooting good in the AM. Afternoons can yield good hunts and are awesome for learning. You may find a consistent X one season that is high and dry the next season.
Scout, scout, scout and then hunt. I know sometimes that is hard when you have a career, but the more you are in the field the more like minded people you will meet. You will get a small group that shares intel on specific spots and then success goes up even more.
