whatever pax...go climb the trade routes there...they are constantly changing...an example is churning...lower on the route, a nice edge pulled off revealing an even bigger two finger gas pocket behind it...higher on the route, some footholds fell off making it harder, then the gas pocket lip broke making it harder...THEN A FUCK FACE NAMED CORY DID DELIBERATELY CHIP A HOLD ON IT, making it easier...but, you see routes do change there from traffic...while scarface doesn't get sent regularly (well, actually it does) many of the successful sends required the climber to devote several seasons of every weekend pounding on it...
Think what you want...i lived there, and i've seen it...there was no active chipping on scarface after it was climbed...whole lotta brushing though...
