5star not true on the 777. the speedbrake is very effective maintaining 180 kts or so down the glideslope with flap 5. So effective that you don't even need full speedbrake
.
I know the A330 is totally different, friends that fly it say their speedbrake is totally useless trying to hold speed down the slope with config 2, they need to take the gear.
But the mighty 777 has no probs.
You either take flap 15/20 to hold the speed or use flap 5 and speedbrake. It's up to you, your situation and your company SOP's.
