Shouldn't be too hard to code in, right?
Bolas would incur a movement penalty of half speed and Quality of Bolas would determine length of movement penalty (same aspects of skills and conditions that go into sling could be used here as well)
Lasso would tether horse rider to his target. again Quality of lasso would determine how long tether.
