The violin or the fiddle requires finger dexterity in both hands. There is a minimal movement in the bowing hand to accomodate the bow so having a bow that is capable of flexibility of slight finger motion seems to make sense to me.

The "cambre" of the bow is about balance.
One way to discover the "cambre" is to place
a finger on the stick and attempt to find the area where the bow can be balanced. A good "cambre" is desirable and I think this may be
three quarters near the frog but I could be corrected on this.

The right weight of the bow is a consideration.
Some prefer a heavier weight for more power and others a lighter weight for more flexibility in playing fast light passages.
