I've changed my 'stick allegiance' many times over the years (at least 30... shhhh!) and in the process bought from just about every stick company (we're talking Vic Firth, Pro-Mark, Vater, Wincent, Zildjian and a few more)
I've found Rohema sticks (and Agner) to be well up to par with the well known brands (I've never had a warped pair - quality control appears to be good - unlike some of the others mentioned before)
With one notable exception - They cost less! Much less!
