I find the Okumas & Compres to be "lighter" than St. Croix as well.
The action on Okumas is also "slower".
You are right, most are rated for a fast action but just how fast it is varies by manufacturer. There are however, some rods rated for a slower action. St. Croix's 7'2" (marketed as a crankbait rod) comes to mind as well as their trolling rod.
