this should be fun...here's a few ideas;
- 2 weights (-/+90kg maybe...), 2 teams, 2 captains
- 1 winner per weight, plus overall winner
- points per pin, team with most points wins
- possible joker card (double points) to be used if it gets too 1-sided, like they use in speedway...
having single pin, double elimination format would suit novice & pro alike.
