Worried I might get too big...

Make sure your are using an AI. This will reduce water weight.
If this is your first cycle drop the Anavar. Why use multiple compounds if you are worried of growing too much? I find people use way too much AAS when they are cutting.
Eat less then your TDEE. Impossible to grow bigger if you are under maintenance. (excluding water weight)

And being tall works in your favor here IMO.
