I have an Aero Storm I use BBO in at 40lbs. It feels both crisp and soft(ish) for a poly at 40. It's weighted up a bit and I am not remotely rewarded with subdued hitting with it. When you swing out, it has amazing spin.
It also seems to last forever. One of the few strings, as well as Revolve, I can play with even when dead(but it's harder on the arm).
BBO is the goat poly. Spin, power, feel, etc. Dies very quickly though, at least the original version did. If I could restring daily, I would never use another string, but that’s not realistic for me. It’s not manufactured in its original form at the current time, but it’s still relatively close. You should try it, but it will spoil you for using other strings.
