In Fisherman is a great read and Doug Stange is a great guy who I keep tabs with via email. For catfishing, they provide some of the best info around.
However many of their techniques just do not apply to Colorado, in particular the Western Slope, because their fish patterns often center around natural lakes that have pelagic baitfish, which western Colorado has NONE of. Pelagic baitfish cause fish to behave totally different up there than on the West Slope, where fish are less aggressive and tougher to pattern, and call for smaller, more finesse like presentations because their are no pelagic baitfish.
