Yes, I always load the TC (even a stock one) just a little bit. Not to the point of almost spinning the tires, but just enough to take up some of the drivetrain slack. For the stock stall, just a few hundered rpm above idle is enough.
I'm not sure what you mean RPM by "slack", please explain? When you let your foot off a stock stalled 4l setup, you should roll forward without any throttle command, no? I figured to add some load was just to get a few hundred extra rpms, not to offset "slack"?

I guess in this context though, the slack is more relating to loading the suspension a bit first, rather than shocking the tires by going from 0% TPS to WOT instantly. I usually get a more useful launch by bringing rpms up from idle a bit, even with the stock stall. So there is both drivetrain and suspension slack (or preload) to be considered.
