I have been using 50% since the summer. While the this formula is really soft and the legato playing with this rosin is perfect, it is often not tacky enough. I was talking to a local friend (who also happens to be a commercial rosin maker) about balancing ingredients, temperature and cook time. When I described what I was using, its playing qualities and what I am looking for. He said that it sounds like less wax in the formula would help (assuming that beeswax is used) but that the tradeoff would be that it would lose some of the smoothness I enjoy with the Leatherwood.
Have you also tried the amber in the 40-60% range? I am wondering how the BASS line compares in terms of the stick/grab
I've been using the BASS version. I have the two cakes of the earlier stuff but this seems to work better for me. Together with the Tempera strings it's a great combination. I played an orchestra rehearsal last and didn't have to reswipe through the whole thing and the only dissatisfaction I had was with my own playing. I hate it when I can't blame my equipment.
