Straightwire Virtuoso H

I need a pair of speakers cables for a pretty long run - 25 feet. I am currently using Straightwire Rhapsody S speaker cable but I am thinking of going with a slightly higher grade cable since the length is long. I am connecting Vandersteen 5As to a Modwright KWS-150 SE.

Any opinions on the Straightwire Virtuoso H cable? These will be bi-wired.
