The Arcus S5 Octagonal was the final choice for me after reviewing several other models. I compared it to a Pernambuco Silver Model by Arcos. It was comparable, but for me the light weight and agility of the Arcus S5 was my choice. It gave me a richer sound with little effort. I am very satisfied with my choice. I appreciate JS Fisher Violins for their help with choosing my new bow.
