not mon morning qbing but - on the 170 when you add gust factor plus ice speeds with high landing weight you get Vapp speeds approaching 150kts. That can be a real bitch when your down to around a 5000ft runway left for rollout.
in these situations (many speed additives) it is wise to go with flaps full landing - you decrease Vapp and ref by 10 kts. -10kts at 70000lb landing weight helps, remember momentum(or energy you need to dissapate on landing) increases with the square of velocity.
