I've been looking to get new strings and have read and listened to everything I could find about every kind of string. I play arco and do a lot of solo work (in orchestra tuning) and I play in two orchestras. So far the only strings I've ever used in my life are helicore orchestra, and on my new carved bass I feel like it could get a better sound with a set of strings more tailored to my like likings. My carved bass is also a bit on the darker side tone wise. I like having nice bright high notes in my solos, I do a lot of baroque and I think bright tones make basses sound more cello like maybe, I also like the sound basses make in solo tunings which I understand to be much brighter than in standard tuning. With that in mind I've pretty much decided on Pirastro Permanents. But, I also like having a bit warmer tone on low notes so I wonder if getting flexocor on the bottom strings would give me that but still blend well with the permanents. I'm not sure what I think of Spirocore, and I also don't like their price, and their higher tension. What do you guys think, do you think these strings will give me what I want? Is it okay to mix strings right away or should I potentially waste time and money on a single set of Permanents first and then see what I think? Also this is kind of the sound I'm going for, he is playing a full set of flexocore in solo tuning for this video.
