Demetrius,
Players including yourself make it a point to not play on the 7 foot tables in favor of the "big table." Now the reasoning may be vastly different, but I am going to say the "kids table" excuse ranks fairly high.
You are currently a 722 Fargo Rate player. I see a 727 in league & local tournaments all the time along with another 719. There are many 700 plus or minus players in the Rocky Mountain Region. So don't take this as a disrespectful statement, but "professional speed" doesn't mean a hill of beans to me.
So as for being spot on - maybe there is a point where things don't jive with what "pro speed" players believe or want to hear.
Here's what I have seen in the past 25 years or so in my local pool room going from very forgiving 9 foot tables along with Valley 7ft tables to now 7ft Diamond pro cut & (1) 9ft pro cut Diamond. The gap may not be as far apart as one would want to believe between 7ft & 9ft tables depending on make, model, setup.
Big table pockets can play like a 5 gallon bucket that you pick up at your local home improvement store. Pocketing balls on a 7 ft table at times can be much more difficult in actual play.
May not be the case with the OP's two choices, but again the gap isn't that far apart imho.
