I own both sitka/EIR and coco guitars, and love them both. If I had to choose between coco and EIR, I'd probably go with coco because I think the overall balance is flatter than what EIR delivers. But I think I got the best of all worlds when I paired the coco with sinker. You didn't ask for my opinion on this, but really, a coco/redwood combination is mind blowing.
