Just a final thought on the blues after a few weeks.
1st: Bowing is much easier. I don't know if it was me adjusting , the strings settling in or both, but bowing: non-issue. In fact, kolstein and pops work fine as rosin, but I prefer the kolstein.
2nd: Coming from my prior setup of obligatos and spirocore, the attack of the blues seems quicker than the obligatos. The obligatos feel more springy, rubber band like they stretch as you pull them with your fingers to pizz whereas the blues seem like they are more solid. Kind of in between spiro and obligatos as far as feel. It is not a good or bad thing, but just something I noticed.
3rd: Sound Pizzicato: I kind of miss my obligato/spiro setup a little. The sound achieved with that combo and the bass brought a more complex tone and character. The blues are cleaner, but not in a sterile way as the bass' character still comes through.
4th: Sound Arco: I prefer the more clear defined sound of the blues. Maybe it is partly my new bow, but I find they project much better and it is easier to pitch with the blues. Know though that I am no "Joe Arco" lol.
Hope this helps future string hunters.
