Actually, every scheme keeps the weaps after a draw...
Ropers/rrs = Only rope/chutes... so no changes...
The thing is, it is considered as 2nd round, so you have to press the button New Match to restart without keeping the weaps earned in the 1st game. Then you can also change the map etc.
Obviously, when you make a draw, you want to play a totally new game. There's no 1/2, 2/2.
