What's the best way to "Return to LZ"?

What's the best way to (all units automatically) "Return to LZ"?

Is it better to select all the units and hit the "Return to HQ" button, the "Return for Repair" button, the "Go to Transport" button or just  click on the landing zone?

The reason i ask is that sometimes the units take awhile to register themselves at the LZ and then the time runs out (i like to play to the max time). I haven't managed to work it out yet.  ::)

when you're sending 30 or more units to the lz at once, they'll stop when they're impeded and when the group as a whole is near the lz... so what you want to do is just select them all, send them to the lz by whatever method, and then once they arrive, select stragglers and move them in closer, and repeat. i'd also advise saving the game as soon as you need to return to the lz, as well as doing research during that time -- it's easy to get ahead in the campaign by sending all but one unit to the lz, doing research the whole time, and sending that last unit to the lz with 10 seconds to spare.
