I have a VPI, the arm doesn't bother me.
I rotate carts every month or so and it's like setting up any other cart like on say a Rega.
Now that I use a unipivot, it kinda bothers me that a gimbaled arm can only track in two axis, while the unipivot is free to track along a theoretical infinite axis.
Last time I looked, most records aren't perfectly flat.
