Put an agular surface at the floor so they CAN'T jump,it would only shoot you back at a 45 degree angle.

As you can see if they change it from normal to hardcore you need to use turbo for height. ,then the lesser, definitly can't do a jump.
And remember if they change the grav and things on there machine,your plans will go undone.or the translocator.
