My first was a Meerschaum and I have since ordered some 9mm filter meerschaums from Altinok. I also purchased a few 9mm pipes from websites. Vauens, a Big Ben, a Jobey, and a Stanwell (I bought cheap pipes just to try it...but I am going to invest more in some Altinok Meerschaums....since the wife INSISTS I do it!)
In fact, if you followed the thread about my wife wanting me to clear out pipes...one thing I intend to do is clean out a lot of it to make room for more 9mm pipes!
It was different at first, and when you go filter, you have to realize you are adding an expense and a step to your smoking. But, let me tell you about the benefits I have enjoyed!
Initially you will think tobacco is weaker and the draw feels funny. That is just part of it.
After a few days I noticed that tobacco tasted better. I also noticed I didn't have what I call "Pipe Mouth," you know that tobaccoy aftertaste. Now I brush my teeth three times a day, but switching to filters changed the way my mouth tastes. Maybe there is less "stuff" getting to my mouth, but I notice more subtle flavors in my tobacco, the hints are clearer. I also notice I enjoy my food and drinks better. It really cleans out your mouth and awakens your taste buds!
I like some pretty moist aromatics...and I have not had a bit of moisture drip through NOR do I get any bite. The filter can really absorb some "junk"
When picking the filter there are a lot of options. There are paper filters, like a Grabow, charcoal filters, and even filter made of Meerschaum (so you can get some of the benefits of Meerschaum in a briar pipe!)
My personal preference is for the Big Ben filters, and I order them in a bag of 200 from 4noggins.
If you want to try 9mm I would suggest the Vauen starter kit. It comes with a pipe, cleaners, tamper, and a leather bag. They are $89.95 at this link.

If you want to try 9mm stick with just the 9mm for about a week. If you don't notice a change, go back, but the change happens and it is gradual.
Just my $0.02!
