That's something I have been thinking about. In my mind, this is how I group the stages, on a scale from Starter --- Counterpick --- Banned:
~~~
Starter
Battlefield
Final Destination
Smashville
Yoshi's Island
Starter/Counterpick
Pokemon Stadium 1
Lylat Cruise
Counterpick
Halberd
Castle Siege
Delfino
Pokémon Stadium 2
Frigate Orpheon
Pictochat
Counterpick/Banned
Brinstar
Jungle Japes
Rainbow Cruise
Pirate Ship
Luigi's Mansion
Norfair
Hanenbow

Starter - These are the stages that I consider most Neutral. They should ALWAYS be included as Starter stages.
Group One - These are the stages I consider most Neutral, in the sense that they don't have any complex parts. However, on their own, they don't make a good Starter set.
Group Two - YI isn't exactly a Neutral stage, since it has a lot of aspects that deviate from the common concept of Neutrality: a non-flat surface; Shy Guys; random ghost-platforms; and a tilting centre platform. But, it's presence in the Starter list is important, as it balances out the stage choice for some characters (such as Diddy, ICs and Falco) who would otherwise be fought on a stage that they would use as their Counterpick.
Starter/Counterpick - These stages are suitable for Starters, but have aspects about them that cast doubt as to their viability as Starters. One goes to CP, the other to Starter; no big deal.
Group Three - Lylat is a great stage....that tilts.The tilting ****s up everything. PS1 has two/three tranformations that are probably deserving of CP status on their own, but since they last for a short amount of time, it makes it borderline.
Counterpick - Standard CP stages. Should always be included.
Group Four - They provide advantages for the losing player. I don't see anything wrong with these stages that makes me question their viability.
Group Five - Whilst these are still fine CP stages, there is just things about them that mean I group them as somewhat less CP worthy than the above: Frigate has no ledge on the right side, which ****s with recoveries that use tethers; Picto...has a lot of transformations, and that just bugs me for some reason.
Counterpick/Banned - Stages that IMO are treading the line between being viable and not. With these stages two rules apply: If you put stages from one group in CP, all the stages in the above groups are also put in; and all stages from a group must go in if one does. Note that all of these are accpetable for Teams play.
Group Six - I'm undecided as to whether Brinstar goes with the group above or below it. On one hand, it is a stage that provides a good CP for certain characters, on the other it has lots of stupid **** going on.
Group Seven - IMO viable CP stages, but against some characters you pretty much have to ban it or it's an autowin.
Group Eight - Kinda viable CPs, similar to the group above but they all
have things that make me question that viability: LM, circle camping, semi-cave of immortality; Norfair, lava, ledge camping, stalling to some extent, and LAVA.
Group Nine - An interesting stage, in that it is a good doubles CP. It's never going to be in singles, but in doubles works.

The issues I have with choosing the stage list are:
1/ Choosing a 5th Starter. IMO a 5 stage system in the best, which means that either PS1 or Lylat need to be included, and thats an iffy decision. A 7 stage system could also work, but that means that a 7th stage needs to be chosen. Urgh.
2/ Brinstar. For the most part I group Brinstar with Picto/FO, but I'm beginning to think it belongs with JJ/RR.
3/ JJ/RR/PS. On one hand, they are good CPs; on the other, they can be stupid.
I am tempted to put Brinstar with Jungle Japes, Pirate Ship and Rainbow Ride, and then put them all in the CP list.

Also on another note, I am open to the concept of using Custom Stages as a tournament standard. It would solve the problem of having to find a7th Starter, and they could be some great CPs made to tailor to a specific play style or character type.
Unfortunately, because it is, by nature, not part of the base game to start with, it is inherently difficult to objectively make a stage that would work alongside the stages already used.
If there was a Backroom led project to create a set of Neutral/Starter stages, that culminated in a BR-sanctioned list of stages acceptable for tournament use, I would definitely use it.
So yeah. Discuss etc etc
EDIT: I was supposed to be doing homework and I typed this up instead...good one attila...
