Hyper turbo is bit too fast, but normal feels too slow so I prefer midway.For me the faster the better.
I think that the faster the tournament, the better. The frerrols, for example, already take a long time. So the faster the better.
So which freerolls take long time? I think i know answer to that although you probably werent referring to them ...
it is better to open several regular tables and play them with concentration. Fast poker doesn't leave you time to think when you play multiple tables.For me the faster the better.
