This year I have introduced a higher strength white thread. Both perform comparably but there are some differences.
The white thread is approximately 50% stronger than the orange.
The orange bobbins contains 300+ yards of thread whereas the white is 200+ yards.
The orange thread glows under a blacklight whereas the white does not.
I see no difference in flight characteristics.
I have had great luck using the orange but this season I am going to use the higher strength white.
