Change Player Speed on Ladders

[Sexacutioner 0]

Ok, this is a shot in the dark here, but is there any way in config or something that you can change the speed in which a player climbs ladders.

Here's what I'm working on. I'm making a sniper type multiplayer island area that is an area with a bunch of steep cliffs. I want the players to be able to climb up to different areas of the cliffs for different sniping positions so I decided to just make some big ol' ladders in oxygen. The only problem is once I made one huge ladder, I realized that it was just as fast if not faster to crawl up the side of the cliff so it kinda defeats the purpose of having ladders. Any ideas?
