I agree with others stating you are getting decent flex. If you have the antirock, don't disconnect. Sure you may see a bit more flex, but who cares.
Keep in mind that massive flex isn't the holy grail of wheeling. Traction is. With lockers, you can not have much flex at all, have two wheels in the air, and still continue forward momentum. Sure, that scenerio isn't as stable, but only one wheel in the air at crawling speeds isn't a concern either.
