Having thought about this a bit, it"s a struggle to manage to play the (L) games at 10pm. They attract such a large field size, that you are playing for 10-12 hours to final table, which is also into the following morning.
And the fact is, you could play for 6-8 hours and only return 2-3 times your buyin.
I think I might stick to the earlier ones, or make sure I satellite into the (M) games and at least then feel I"m getting a reasonable return if I cash.
