So I've been using my Tinsky pipe for a while now and had to ream my bowl 2-3 times already. What's concerning me is that since the beginning the cake always looked oily/wet and it seems really fragile. Some pieces of cake always break at some point. I smoke the pipe like once a week and only va blends and no aros. I smoked a lot of VaBur in it like ODF. I always dry my baccy too. Is this normal? Am I doing something wrong?
