Curious of feedback of anyone that switched from GC2 HMT to GCQuad? Or even GC2 to Quad.

Don't use it for gaming purposes. Use it for indoor training mostly club fitting / range mode.

Do you see any improvement on accuracy or ball projection for carry and shape?

My GC2 seems to be more draw biased versus outdoors which I am learning other people experience this also. Stock shot is draw and inside it draws more than outdoors. Foresight recognizes this.

I think though its the same algorithms in the Quad versus GC2 HMT.
