STIGA WRB BLADES

the balance is different, you must try it to find out, personally I dont like them that much. The blade feel heavier....

ive been using wrb blades ever since.. the head heavy char. of this blades can be bothersome at first but they can be overcome by getting used to it.. head heavy blades IMO are good for looping and driving since it adds momentum to your shots.. also i like to have vibrations (others call it feel)
the reason i stayed away from btty carbon blades like gergely, schlager, sardius and primorac is beacuse i really can't feel the ball in my blade since these blades are too stiff.. vibration and fell are subjective and depends on every player but i like to have them in my blade.. i have used stiga tube off wrb, tube carbo (less vibration but very good looping blade), carbo kev
 wrb and currently tube alu wrb

mece... well imo they are the same.. as what i have said some call it feel but others call it vibration esp. when it bothers their hand during play

i own several Stiga blades and all of them are WRB.  i agree with yogi_bear, while there are players so bothered by what they call vibration/feel there are also those who are not comfortable with very stiff blades. i really do like my Stiga WRB blades. 

there is annoying vibration on cheaper blades.
