The problem is, no one really knows what to recommend for you, because
no one uses that kind of stadium.
Even within the Hasbro meta (which is pretty underdeveloped anyways) testers avoid that kind of stadium like the plague - the cracks and lack of Tornado Ridge, plus its small size and itty-bitty pockets all make it a poor choice for battling. So, everyone avoids it - and now there's no one to suggest what to use because no one uses it if they have any kind of alternative at all.
However, if we make a few assumptions about the stadium's theoretical metagame, we might be able to come up with something.
Assuming:
-Using anything other than an S-series tip is suicide
-Stamina beats everything
-we can figure something out.
Libra is a horrid Stamina wheel - use Cancer, Cygnus, Hades, Aquario, Bull, or even Virgo (that's best to worst there) instead. Use a Hyperblades Phantom if you have it, or, if you don't have Hyperblades, Burn or Earth. For Tracks use AD145 (DF145 or a standard 145 can be a substitute). And Faces don't really matter, unless you have a scale, in which case use one that's light - like 0.9g or so. For the tip use either ES or MS, as both of those should be low-friction and get high Stamina.
