YGK XBraid Upgrade x8 (formerly GSoul Upgrade) is quite possibly one of the best braids on the market for finesse fishing.
 
Amazing performance made possible by high-density pitch manufacturing method x WX8 method x GP processing x HST processing. 
 
In general, when PE lines are assembled with high density and fine pitch, the wear resistance increases and the straight line strength decreases. On the other hand, if the yarn is assembled at a low density and coarsely pitched, the yarn will become straight, increasing its linear strength and decreasing its abrasion resistance.
 
X-BRAID UPGRADE achieves both of these conflicting performances at the world's highest level, and is a high-quality, high-power product in all categories that complies with the "PE thread thickness standard" established by the Fishing Line Subcommittee of the Japan Fishing Products Industry Association. 
 
*The WX construction method is a construction method in which when assembling into 4 or 8 strands, the twist direction of the raw threads and fibers is symmetrical on the left and right, or all 4 strands are symmetrical. This construction method, which is also applied to cables (lifelines), provides exceptionally strong stability and improves the straightness of the line
