E or E/C to match Orig Flex G, D, A

[Scott Pope]

Probably not, but T-I now also makes a Bel Canto extended E. I have no experience with it; as a matter of fact I discontinued the Bel Canto regular E string on my bass in favor of a Spiro 3885.5W. I only say this because of the different worlds of pizz and arco. Since it did not do well for me at all as a pizz string, but felt good for the minimal arco I do, it might coordinate with what you're looking for in a long E string.
