i was hopping that i will solve the bow problem with this one for some time but ha it didnt last so much ,as soon i got him couple of hairs cutted,since i am playing every day for couple of hours the hair started to cut much faster and i am not that agresive on stings, i can past on that since there is a lot of them ,the thing what is really bad and i was extremly careful to cut them with scissors leaving small part to stay ,not pulling for the core,but still after 3 months of playing now if you want to tight the bow ,until the very end the hair wont stay flat and it is loose and that is the most anyoing part you see,but lets get real,Cello is an instrument which requires upgrades all the time ,Carbon body is really nice and light ,comfortable and i think that is the only thing you have payed,as for the hair it is one piece of shi...but yes if you dont want to spend hundreds like i did go for this one maybe u ll have more luck
