The Nimbus is gorgeous! If I had the money, I would be all over it. I have the Stratus and the double braided handles are not bothersome to me at all. So I'm pretty sure the single Nimbus handle isn't a problem.
i have the stratus pm and nimbus gm and am loving both of them. i dont think the nimbus gm is big for me even tho im not that tall to begin with it slouches with i sling it on my shoulders so that made the size just nice on me!
