you meant phone orientation right?
I dont like to flip my phone using iBulive mount with vent mount, its feasible but it will work better on circular magsafe holder
I ordered this kind of vent mount
I assume its metal hook but it could be misleading and made in plastic, anyway i'd prefer that kind of vent mount, much more stable than iBuliv stock vent mount

The other solution could be using an adhesive tape holder with ball mount

I dont know if you can both remove magnetic holder out of ball mount and if ball mount would fits to your magsafe model
If it was the case, buy some industrial double tap or gorilla tape, it will hold much stronger
