Lennie, the first one is really nice-looking.  I'm heading in your direction today, going to a funeral in Vandalia.  Hope to get home before the snow hits.
Badger, It is interesting to see how the mass formula comes close to already finished bows--a good test for sure on these bows that are extremely well made.  I'm sure that the bow material is a factor.  You mentioned a conversion factor for the bamboo backed bow.  Have you found a need for other conversions due to materials and/or laminates, etc?  Jim
