I just got an extension on my double bass and was wondering what string might work the best with my extension. I have a set of '92 Flexocors on my top three strings and am currently using a temporary Permanent extended E string that I have to return after I buy my own string. I'm looking for something that will blend well with the top three strings and the bass is only being used for arco. I'm looking into getting a stark Flexocor extended E but it's going to take a little while for Quinn to get one in stock, though they said they can get their hands on one eventually. Lemur told me on the phone that Flexocor extended E strings in the stark gauge are actually discontinued. I read some of the posts here about long E strings and it seems that a bunch of people like Spirocores. Based on the posts I'm not sure if the sound will be too bright. I'm a complete newbie to extensions so any help would be great!
