Plugin Help 1v1 Plugin that isn't so complicated?

I am looking for a 1v1 pvp plugin that isn't so complicated. Before you go and recommend PvP 1vs1, I have already tried that and though it works, it takes a lot of commands to get working. You have to do /1vs1 duel <opponent>, /1vs1 accept, and /1vs1 join. I want a plugin that lets the user do only 1 command (ex. /duel <opponent>). Then I want the plugin to find the next open arena. I have arenas made on my server, its just I want the plugin to find an open one, somehow. There has got to be a 1v1 plugin out there that will do that. In essence, I want the 1v1 plugin Woodycraft has. Simple and efficient. Is there a way to somehow create virtual arenas for the players to populate, or do I have to literally create multiple instances of the same arena...?

I would appreciate any help, thanks.
