First off I do like your list, that said I feel that Andy has some strengths and weaknesses to CT for this type of list.
Strengths being the ability to play siphon, and it being easier to get your cloud breakers online. Downsides are 1 less MU on full rig to play with, and less pure card draw.
To be honest on the consistency issue I really don't know how much of an advantage it is to start with 9, verses starting the game with one less unseen card from your deck is (Andy has 36 cards unseen at the beginning verses CT's 35). It looks to me like CT would have a slight edge on seeing a singleton card during a game versus Andy (assuming its not a card that you would strictly mulligan for).
That said it could all be that I'm an old stimshop player, and am very comfortable with it and its match-ups, and on the other side is that blue color that I very rarely get out of the binder and sometimes even have to look at what the cards do.
edit: can't english tonight.
