There is almost no review on Winex string, so I think it's good to leave a few words here. Sometime ago, I got several reels of Winex BS 70 from ebay, price is less than $10 per reel including shipping. Retail price is perhaps $70-$80/reel, I guess. After several games, I found this string is very well made, enough power and good control. I feel my MP99 + winex BS 70 is much more power than my NS9000 + 66UM. Maybe the 66UM is losing the tension, but still this cheap (cheapest ??) string is a big surprise to me. Only thing that I don't like is the hitting sound, not as lovely as 66UM. I also have a few Winex Ti-80, will try and report later.
