The old spokes (40+ years) are an odd size; 307mm. I used an old Park Tools ruler that has a specific hole for hanging and measuring spokes. To match that exact length bumps the price from $1.00 to $1.40, at least on the Wheelbuilders site. Most sellers want to sell even length 306, 308 etc.
There is a seller on eBay that was recommended here on Bikeforums, "childhood_dreams", whom cuts custom lengths, very affordable but they spokes appear to have no brand-name. I plan to discuss with my buddy-mechanic before buying. I just wanted to figure out if there are specific brands recommended or not recommend to couple with high flange. Thanks to those that respond.
