I know Ross's Jump will have a -6 mod for speed, but that's something you apply at the time of the roll (since speed can often change), not on the character sheet. Also, I think that the -6 for speed should not stack with the doubling of the jump DC for not having a running start.
Wow, that's a small keep. Great!

I think. Anyway, no need to worry about going from a wall, now, we can just grapple that baby if we need to.

Or just climb up the wall, although I would guess it would appear to be a pretty tough climb (DC 20 to 25?).
