Any good string to use for long c-string with Bel Canto?

[Brownbass]

Want to know what players are using with a set of Bel Canto strings for a extended low C (long E) since Bel Canto does not make one yet? Would a Pirastro Permanent be a good choice? Obligato? Any suggestions.

Thanks!

I bet this could be better answered in the double bass forum.

I wish I could lend advice but I got nothin here...
