My first Polaris experience was on May 2017, SFO-SYD. PDB champagne glasses were weirdly shaped - I wouldn't mind these being eliminated. I loved the chocolates handed out at the beginning and end of the flight. Also appreciated the wine tasting (I tried 3 red wines poured in small glasses), though I limit alcohol consumption on flights. I think having all wine bottles on the cart is helpful for passengers to know what is available - sometimes certain wines run out. I skip the mid-flight snacks, so hot bites changes wouldn't affect me. Mattress, pillow, and blanket were comfortable. The 787 lie flat seat is solid, and good for sleeping with the main issue being they shake when someone walks by or the person next to me moves.
For long haul flights in business, I'm good with a lie flat seat, ample storage space, aisle access, friendly crew, and edible food.
