My experience (from not advancing due to one stupid win short) was that round robin works great, much more preferable to best game. I love matchplay. But on first playoff round, only top 2 advancing... pretty brutal.
I think my main issue was with the classics, more specific: 3 balls only. Yeah im not that skilled yada yada and i know for example dpm have 3 balls clasics, but still think it adds to the random element. 4 attempts does not make out for house balls. Anyway, had a great time in borås, have to practice more, crawling back to norway =)
