I got this hickory stave from Hickoryswitch.  It was already de-barked, but I wanted to clean it up a bit so I could fine the vertical grain better for laying out the bow.  I had finished cleaning over half the bow when I noticed what I was doing.  I was scraping down through the cork like consistancy wood to the smooth wood.  A light came on.  I started paying attention the sound and feel of my scaping as well as the visual texture.  Though the corky wood sound was low pitch raspy.  As soon as I was through it the sound changed to a smoother high pitch sound.  The feel of the wood under my scraper matched the sound.  Woohoo, I'm chasing a ring! completely by accident.  

  Am I safe to assume this?
Now for the questions:
1.  It's a shag bark hickory.  There are ridges along the back of up to 1/8" in heighth.  Should I leave them or smooth them out? see first picture.
2.  Theres a couple of worm marks that I can't work around.  Is this going to be a problem?  Should I attempt to go to the next ring or plan to back the bow.
3.  I'm looking to build a bow with a slightly working handle.  Here are the dimentions I'm thinking about.  Will they work?  Is this a good design for this wood"
68" t2t, 1" thick at the handle, 7/8" wide handle, 4 1/2" long handle.  2" to the fades. 1 1/2 wide fades tapering to 1/2 at the tip.
I'm looking to build a 45-55# bow @ 28" draw.
