They have LARGE size pipe all the time. HUG! I would strongly suggest searching their web site and then giving them a call. They can fit your needs and at a good price.

I'll second the MM General. They're super cheap and have big bowls. Most classic handmade pipes have considerably large bowls, but you will pat a premium.

I actually prefer medium sized bowls smoked very slowly myself. I can make a solid medium sized bowl last upwards of am hour and half.
