As for the CRJ seating, I was just on a flight last week in Row 13 (exit row) You have great leg room but the seat bottoms are definitely shorter and maybe less padding than the non-exit row seats. Row 1 on the CRJ might be a better bet.
I can't say I'd choose row 13 again even though I'm 6'3 and could use the legroom. The bottom cushion was very uncomfortable for the 2 hour flight to Billings. 1 hour would be doable.
