It depends. Once a logical is built, you don't have the same overhead to create the access path as you would with OPNQRYF. Dynamic Select affects this, but it's been awhile since I've dealt with that. If this is used "often", it's probably best to define a logical. If rarely used, like once monthly, just keep using the OPNQRYF. If used in a lot of applications, even if rarely, probably easier maintenance to define a logical.
