Got a reply from BCY.....

Dear Steve,

8190 has been popular with recurve shooters. I do not know why Win and Win said not

to use it. Basically 8125G is made of SK 75 dyneema, The 8190 is the newer SK 90. It

has less creep to it, little less elasticity. The 8190 is a slight upgrade over the 8125.

452X which has Vectran added, can be rougher on the limbs. 452x is more popular

with compound shooters. But there are some that prefer that for recurves.

Many top Olympians are shooting the 8190 with no problems. Some still prefer

the feel of the 8125. So it's a personnel choice.

Regards,

Chris 2014

The toughest bowstring material ever made. Stability, speed, safety, durability, reliability.
