A couple of HRs unique to our league (I've probably mentioned them at some point but here they are again):
If a blocked player is knocked down and the Armour roll is 2 (that is, two 1s AKA "snake eyes"), the downed player bounces back to his feet as if nothing had happened. (Elf: "HA HA HA! Stupid ogre! Thought you could hurt ME, eh?"

) And since AV rolls can't be rerolled...
We use the PBBL Team Rating rules (simpler to add cash value to a player as he improves, plus TR calculation is WAY easier when a coach doesn't have to figure in 1/5 of the team's SPPs!)
We use our own kickoff table, and the "Stadium Features" and weather-by-climate tables JK Lewis created. We do not play in random stadiums, each team has a home.
When a missed pass (not a fumbled pass) scatters, it scatters a number of times from the target based on the length of the attempt, thusly;
Quick Pass scatters ONCE
Short Pass scatters TWICE
Long Pass, Long Bomb and Hail Mary scatters THREE times.
Mostly we go by LRB 4, though, except we use the Ogre team with Snotlings from the Vault rather than the Ogre/Gobbo combo.
