Vas Spanos is a first-rate teacher and you can learn a lot of stuff from him - both practical and theoretical - that you cannot find in print (e.g. blackjack books, web). You can easily earn back your investment in his classes shortly after start playing in MN casinos.
The number of indexes you will be asked to memorize should not scare you, because it can be done easily with practice at home or during driving. His advanced strategy is very powerful and works in practice.
You will also learn valuable practical tips (e.g. when to add a hand, exploit cut location, betting spread, when to change tables and quit winner, etc.). He can also update you on the status of MN and LV casinos. He shares the feedback of his plays and his students' money making performance.
I am sure that if you take his class and follow his instructions you will do great in blackjack, as I've done myself. You don't have to be a rocket scientist. You just need to be methodic and patient.
I highly recommend Vas Spanos class.
