You should increase the amount of times you are able to extend the map when the vote comes up. 1 extend sucks especially when going for a wr/top10. Should have the ability to go up to 80 minutes, I think every surf server has this and it's strange that it's restricted here.
*EDIT*-Also the end zone of surf_heaven is way too high, it should be on the floor of the last hole
-rtv shouldn't be possible for the first 5 minutes of a map, so people don't just rtv one map after another
