2. I don't like the ergos of shifting while standing, while climbing, on SRAM. Having to reach back behind the brake lever is a tad contorted to me. While on the hoods, Shimano's brake lever shifting is right where it ought to be. YMMV.
This is what you should do when shifting, no matter the group. And it becomes more automatic the more you ride.
That said, I've found Red shifting to be very positive and reliable.
