If it's not finished yet, you have many options. Since all my bows are built for HUNTING I darken them up before finishing. On the BBOs I've done I take some Zar wood stain, not Minwax Wood Finish, and put a light coat on the bamboo. Let it dry and then take a cloth and wrap it tightly around your finger. Stick it into the stain and just tap the rag across the back from handle to tip. You can adjust the pattern or the darkness by going over it a second time. Or experiment, Make it darker near handle and lighter as you go to the tips. I also wipe a couple of light coats on the belly and sides of the bow before doing the boo side. After letting it completely dry. Spray on some Satin spray Poly, 4 or five coats can be applied in an hour. It drys very fast. Then hit it with Johnsons Paste wax. You'll get a durable satin finish that is impervious to water. I'll take a pic of a couple and get em on here.
