Ya mate , I have alot of Brigs and I like em. The filters work well and yes the draw may seem a bit restricted but it really isn't. Does not take much draw for a Brig. Here, however is a bit of a tip. As you use, and wash the filters under really hot tap water, I do find that after a few washes, the filters may swell a bit from use. I take a bristle cleaner and run it tru the filter after it dries. Just helps to keep them open a bit more. Brigs are good smokers and they WILL take a cleaner all the way to the bowl, mid-way tru the smoke. You just have to bend the cleaner and practice quite a bit untill you get the knack.
Always remember, and please don't ever forget (taken from Snyder off One Day at a Time), no pictures equals useless post hahahahah
