Thanks Don. It's the only unit I took on the trip. The S10 doesn't sufficiently differentiate itself to justify the extra weight in my tightly controlled packing regime. We fly hand-luggage only.
Yeah, the A12 28 is amazing but I haven't touched mine since I got the GRD4. I like the S10 tho'. The P10 I have no clue about as I have never been a zoomie guy until the S10.
Your nailing it for sure....
