If you go with the non-lock up converter you'll save some hassle with the converter engagement/disengagement switches and wiring. There's little difference in cost but much more fun to drive, for me at least. You will lose 1 or 2 MPG but I didn't care about that!!

And performance too. Lockup isn’t as much performance oriented but I have a 4500 stall converter so I wanted to lock it on the highway. But wiring the switch was easy. Just one wire and done. Not much complicated about that.
