I have been using Rohema drumsticks for 3 years and I'm more than satisfied. Great quality, very durable..
I haven't been used LY737 model 'till now and my first impression for this model is for any other Rohema model: great!
Nice balance, it feels very nice in hand. Very similar to SD4-H (which are my favorite), slightly thicker, much (round) bigger tip, and slightly thinner and longer neck.
Info from official site: What is special about this drumstick is that the shoulder area is strongly tapered. Its weight is mainly in the grip area and the LY737 offers the drummer a higher rebound and more control. A slightly elongated but spherical tip ensures the right ping!
