I think I would prefer this one with RHW
Saw this at the boutique and it is purple/plum, though it looks brownish in this photo. If you love the GHW and the size (though for my frame, I'd go with old medium and I prefer RHW or silver), go for it!
Personally, I would prefer the old medium size too.. but they didn't have that in the boutique.. nor do they have it with the RHW.. When I carry it, I was really tempted because it looked really good on and I'm a sucker for purple.. I already said that!
