I've learned a TON since posting this topic. Both on here from helpful folks as well as doing my own research. Please excuse my early ignorance on this topic.
It is now my dream to own a full sized 12ft Russian table. I have a passion for this sport and would love to learn how to play. Sadly, there are no Russian tables anywhere for miles.
I also wish there were some better resources for following this sport and well as supplies for international enthusiasts like me. This in pretty much in the dark in the US. Occasionally you might see Snooker or Carom (3-cushion), but Russian Billiards is almost a never.
I do own a set of 2 1/4" Russian style billiard balls. I really only wanted these for the novelty of playing on an American table with a unique set of billiard balls. As for actually playing Pyramid, I would love to someday get or build a 12ft table with the correct 68mm ball set. There's no other way to really experience this sport.
