Oh, I have no rosin problem. I could enjoy playing any of the rosins mentioned, I just dislike some of their characteristics. I do this for the fun of it, or else I'd stick with the Oak. In Sweden, Nymans, Carlsson, and Pops are what people play, and when I first ran into some Oak, I decided it was time to look beyond that horizon. It's like trying strings. You may like a set, but you won't know just how much until you try another one!
Plus, rosin is cheaper than strings, but no less exciting.
Just to make things clear, I am still studying, although I have some gigs every now and then. Pöllmann bass - a rather good one, if I may say so - and a great snakewood bow. My first proper bow is in pieces. That one was really good, too, but the current one is better.
(By the way, I think the Carlsson cake I had had been lying around in the violin shop for way too long. I recall no stickiness whatsoever, and it didn't run.)
