BG70pro? Bg68Ti sounds amazing and its soft. Durability is average. Abit less than the bg80 i'd say. It is a slippery string though
I used to play it when I was young on my beloved AT700 @ 13.5 (winter) or 14 (spring till fall) kp. Three rackets (in rotation) needed a new stringjob every other week (yes, all three). That's a lot less durability than BG80 in my experience. Slippery wasn't a problem for me and I did (and do) slice a lot.... Maybe the tension helped. Anyway, it's a long time ago and I prefer harder feeling strings now.
