^ Lol, especially going up them. Going down, I use the "Let go, grab again" method just like 1-5. Which, considering she has to re-orient herself on the ladder, may end up making it take just as long anyway. But at least it feels quicker.
In all seriousness though, I like the ladder speed as-is honestly because it looks realistic. If it were sped up even a little, I feel like it'd look a little ridiculous.
