I've been using 050 soft rosin and I've really enjoyed the dark sound and grip they bring. I do use more swipes than pops for the same level of grip but it manages to pull more of the lower frequencies to get a much darker sound that's still smooth. Mixing 050 soft with a swipe of pops gives me the best results IMO. The biggest downside is the lack of packaging like a silicone cup or plastic container. When the cake sat in my DIY rosin saver, it would melt into a pancake shape. Not necessarily a bad thing since its soft and feels like its held it's moisture well. But I had to remelt it into a new block after dropping it and put it into an old pops container to keep it from melting back into a flat shape.
I'm interested in trying the super sticky at some point to see how it compares to pops. What do yall think?
