Got these stats from Jap Tak for the YGK stuff.
Strangely enough when I compared the PE line size vs diameter for the 4 strand powerhunter and the 8 strand ultra, they were identical. Even their new one called WX8 Ultra Dyneema was the same.
PE Size & Line diameter in mm
3 0.285mm
4 0.33mm
5 0.37mm
6 0.41mm
8 0.47mm
10 0.52mm
12 0.57mm
Wallet wise that makes the YGK powerhunter pretty good buying. I've ordered all four YGK PE types before from J.T. (Compact/Pwr hunter/Ultra & WX8) & no probs whatsoever.
I love the stuff and I'm looking forward to seeing how the Daiwa x8 Samurai braid that I have now, shapes up.
