From 1st of January 2009 each type of PELLWOOD drumsticks have allways same weight. This means for example, that if you buy a pair of 5A Medium and after some time you buy another one, the weight will be same again, with 2g tolerance. This brings huge advantage to drummers, so they don´t have to get used to different weight every time they buy a new pair and sticks bought in different time and different places can be combined without any worries.
