Hey dudes you know we have a problem with it.
When you do a normal run you have to kill Brian in Bad Standing, but he is very important for a Random event after finishing the storyline.

So what we do know, he gives the last 5% for a 100% Run.

So when we start a 100% run we let him alive?
or let we him out from this category ?

And we need a strat for Brian, because he send killers to us and we have to chase him.

The other 2 Radom Guys are
Malc and David Grossman

not important shit...

For all Gang Wars we can use Terry and Clay, 100% skill on both dont cares for 100%

50 Birds is not a problem, the most are on the ground so we dont need much a Heli, but if we need one, Helis gives enough at the Tourists-Tours play on the 2 Island.

Angus’ Bike Thefts 10 Bikes 5%
Thomas Stubbs' Dirty Laundry 5 Missions 5%

and do all activities with friend and win!
Air Hockey can be a problem because the control sucks.

in my opinion, 100% is 100% not 95%. dont kill him and do the random event. its the same in gta 4, in a normal run you kill ivan. for 100% you let him run away for a random event.

Everything I see online says you don't need brian's encounter for 100% http://www.gta4.net/lost-and-damned/100-percent-completion-checklist/

If you do 100%, you do everything you need to do to get 100%.
If that includes brian's encounter, you do it. If it doesn't, you don't do it.
It's that simple.

all right

Brian is not needed for 100% so kill him, sparing him will just waste unneeded time, in GTA IV there were Random Encounters that didn't count for 100% because its someone you could've spared or executed so why would TLAD be different?

ok than i've wrong informations
