Do a little searching, I started the same thread just a short while ago and made a short list of strings that I found that are long enough to string through the body and have a tapered B string.
Another Lakland Question.
So far I ordered some strings by La Bella and Fodera.
What you should be looking for in scale is 38", it is usually listed as "extra long"
If you can do without the tapered B, you will have a lot more to choose from.
