Hey mate, my stringer doesn't recommend using BG80 with low tension, I think it's more fair to say, BG80 performs as it is supposed to at higher tension. Of course this comment will cause debate but my friend who is my stringer is also a very good badminton player and has the most beastly smash so I trust his opinion as he can speak from experience. But by all means, experiment for yourself, after all, the only way to find what works for you is to experiment.
I just tried aerobite string last night for the first time and on my AVP and I absolutely LOVE this string!! I was rather surprised. It's strung at 28 lbs by the way.. But the feel, the control, the REPULSION, THE SOUND!!! I only played for 3 hours last night and my game wasn't as on point obviously because I'm using a new string but after a few sessions I can see this string being my new go to. I'm gunna get another AVP soon and string it with my other fave Li Ning #1 to do a side by side comparison. Only downside to the aerobite string is it's about double the price but if money isn't the issue here then I definitely urge anyone to try. I think if I can speak this highly of a string that I've only used for a few hours it's definitely a potential promising string.
All the best
