Polo bike geometry + addons

Totally didn't know about this thread.
I would like to think that the polo world could help each other with bike 'recipes', what got burnt and what tasted good (etc.)

Posted this in the polo bike thread but I guess it's relevant here (#mods are slipping)

I'm still really interested in geo for polo (and still think that LDN has the best knowledge).
Matt mentioned something about the cosmic bikes not nessarily going for the smallest wheelbase? Where I was under the impression the smaller the 'turnier'.
I gather Ryan doesn't think curved seat posts are better. But having the seat over the rear wheel gives better manoeuvrability?
What's the ideal trail?
And BB height?

I know these are all variable depending on many factors, but if you wanted to draw up your own bike, are you just looking for it to be as tight and sturdy as possible?

I appreciate also there isn't a succinct answer, but it's good to chat innit.
