Just be careful.. each instructor teaches things differently, thinks about things differently. You don't want to be in a situation where one tells you something is okay but the other tells you never to do that again. Or one tells you in order to get the outcome you want, you have to do B and then C, then the other tells you no it's all about A and B then G... then you're going to be one confused cookie.
On the other hand, you will learn from different perspectives and different ways, though slight.
It's a bittersweet deal.
