It's slower than the standard one and breaks the heal beam between you and your medic.
So no.

I'm pretty sure that is quicker if you have a good spawn. But ya, that rollout was mostly used when the equalizer was not in play.

No I like having a buff

nope

no it's always slower

I was just referencing this video from a while back. I never have done it the other way. http://www.youtube.com/watch?v=zN2LQbvcN_Y

i remember when demos like solidsnake used to rollout through there

I take this route if I am the soldier equalizing to mid. Do 2 quick rocket jumps during freeze time, reload 2 rockets, then grab the ammo as freeze time ends and walk upper instead of lower. I like that route because it keeps me out of the way when the medic is trying to give appropriate heals near the staircase. It's not really necessary with a decent medic, but it does eliminate the possibility of being in the way as buffs are being given.

I wouldn't take this route as anyone else.

What smaka said.

Your jumper needs to be walking up the stairs so he can start the healing process as soon as the scouts are out of range.

+ it helps if your demo flubs his rollout since the sollies will be taken care of and out of your hair.

What about going demo up top? I haven't timed it but it seems not to be too slow.
Kind of pointless since (if practiced) you can do the side wall jump down to the bottom stairs super quick with no fall damage, and then if you're pro at life you can do the surf up the top stairs.
