Attack 11s get a lot of shit and some of it deserves and some of it is not. I think the main disadvantage with them over Attack 13s is that their higher ride height gives you more leverage over you edges, which means your more likely to catch one and they would ski less flat. I am an aggressive park skier at 125 lbs and have had little issues with my Attack 11s although I kinda do regret not getting 13s honestly. Also apparently since the heel is raised it shifts your boot to be leaning forward as well(I think?)
