I don't know if you're interested, but the last time I was in the Destin, Fla. factory store they had boxes of walnut Brooks Brothers Strands on sale for (I think) $199. I don't know if they were firsts or seconds, but it might be worth an email or call to see about availability:
10406 West Emerald Coast Parkway, Ste. 67,
Destin, Florida, 32550-7105, USA
Hmmm. Are the BB Strands also made on the 65 last?
