Sounds like either your stringer could be inconsistent or it was simply a lemon job Sent from my LG-H990 using Tapatalk
Yeah I've had no such issues with mine tbh and none of the owners here (where I play) have either. Does sound like lemon jobs as Ch1k0 said above.
In the case, I must say I am quite disappointed. The stringer in question is, in my view a reputable member of BC and endorsed by Li Ning.
Small mistakes can happen so easily. One lemon job is not a reason to question a stringer's qualities in general. Talk to him about your concerns with that particular string job and see what he has to say about it. Being a stringer, I highly prefer it if a client gets back to me an addresses that he isn't happy with my string job, instead of saying nothing, being grumpy (worst case tell others about it...) and/or simply move on to the next stringer. I do not want to give out bad jobs. In case one has indeed slipped my personal QC, I would like to know it and for sure would offer a free replacement.
