If I ever build another wheel set it will have 13/15/14 triple butted spokes.
1. If the hub flange holes are big enough to take the 14 gauge threads, they'll take the 13 gauge unthreaded end.
2. Spokes most often break at the bend. 13/15/14 spokes put more material there.
3. Price is about the same as 14/15 double butted spokes.
