<<<<Im curious what you think some of those possible fixes are that would be beneficial to reserve pilots.>>>>

As a line pilot, I can only go off of anecdotal info and I have not been polled, so I have no idea if they are asking about this or what the majority sees as desirable.

For me, it must start with ADG 5:15 for all pilots and then and only then, would I start looking at 16 hour long call in exchange for a 5 hour response time.

That is just an example, I am sure the smart guys have many more ways to skin the cat and pilot desires to support it.
