Good old Weichs!

I Also want to play arco as well as pizz but not in an orchestra. I am curious to how others are using spiros rather than just rely on my own experience.

Maybe a better question might be:

Is the purpose of a hybrid string to be able to play well in an orchestra and a jazz band, just play arco and pizz?

Since I am not an orchestra bassist, it's either arco or pizz for me. I can't speak for orchestra players.
