Has anyone else had this issue?
I have this viomusic woven carbon fiber bow, that I was originally using Melos light rosin. I went to a local shop and asked about rosins for warm weather, and they recommended Bernardel to me so I bought a cake to try out. I went home and took off the Melos with some rubbing alcohol and let the hair dry out. The next day I tried out the Bernardel, and it sounded raspy and awful, but I thought I'd give it another try. After a couple weeks, the raspy is gone and I rather like the clear, edgy sound I'm getting, but the problem is I only get it for about the first 30 minutes of playing.
I have to apply about 3 times more compared to my other rosins, and I get really nice sound and adherence in the 30mins-1hour of playing --while there's billows of white rosin powder flying up everywhere while I play. Once the billowing stops, I'm back to slippy raspy stuff.
I'm wondering, is this an issue with the rosin, the bow hair, or something awful that happened when I did the alcohol thing?
