Looks awesome! Nice save on the bow strips getting out of control... especially with all the darker (walnut?) filler, it looks like you planned it that way (and, yes, everything that doesn't "work out" can be claimed as "part of the design")
Can't advise you on the stems though... I'm just getting ready to start my Raven and haven't decided whether to mess with stems or go stemless.
I'm not sure what you mean here... once the station molds were set, I think they act as guidelines and how far from center each is is (in my mind) irrelevant. Do you mean the strips are 1/4 inch closer to the centerline at station 6 than they are at #9?
