Well that's a bit sweeping! It's a bit difficult when you have no indication of popping the spoilers, or if you do have a spoiler indicator, you most certainly should not be looking at that on a take-off roll! I can't ever remember needing more than about half aileron on a crosswind take-off, and this quickly reduces as speed increases so the drag element is reduced and completely unquantifiable anyway.
So what sort of admission that we were all wrong are you after?
