We are definitely aware, but given our skill level games to 11 would end far too quickly. That's why we opted for the old 21 system. Maybe in a year when we can actually maintain good rallies we will upgrade to 11 :)
It's not a matter of skill, with games to 11 you can play 2 out of 3, which often turns out to be longer than games of 21. Personally I think games to 11 make it more exciting; it's really fun being down a game and then gaining hope when you win the next :)
You can play 2 out of 3 just fine with games to 21.
