What are your favorite bounds? What would you like to see in a bound?

The bounds I can think of are Heaven bound(overplayed classic), zelda bound and monopoly bound. I just played Dark Bound Beta made by apos.. Its good so far.

I would like to see more rpg based bounds where an obstacle would have multiple exits. Those exits vary in difficulty and would help/penalize you. Id like to see more units used for example if you finish a certain obstacle, u can use a inf terran. How about team bound obstacles like 2 players must reach two different spots simaltaneously.

I'm not sure if this counts, but I played a "Bound Tournament" that was my favorite of them all.
