Hello all. I am wondering, filter or no filter? Is this really just an opinion from smoker to smoker? I started out smoking my pipe without a filter and then figured I would try one to see if it made things even MORE smooth. I could tell a bit of a difference I suppose and used one for about 3 weeks. A couple of days ago I took it out and decided to try without again. I have noticed a bit more flavor but overall not a huge difference. So, what do you guys think? Is this an opinionated question?
