Fun fact.
Tourney levels are chosen for their functionality and their ability to keep things level for each player. Very minimum interactions are involved to keep the focus on the players combat and not having to worry to much on the level wanting to get a lick in.
Basic level schematics of choice are the three platform and large base platform design, or just simply the base platform. Basically, Straight line, or Straight line with smaller platforms. These two simple designed maps are perfect for keeping everything nice and tidy.
Tourney players pick a level for it's functionality, not for it's visual appeal. Truthfully, it could be restricted to 3 maps, those being FD, BF, and SV, and there would honestly be no difference.
You are in it to win it, so you will be focusing on your player, not the level.
If you find yourself concerned over the level's flashiness during tourney play, then you obviously aren't focusing on the match, and are not in it to win it.
3-5 levels are perfect for tourney play. At least if there is money involved. Public tournaments are different; do what you want. However, if you are so concerned over levels in a high stake tourney match, then you probably shouldn't be worried too much of playing the match to begin with.
