I completely agree you use what you have and work to a rotation / different pipes as time and funds permit. The entire point of pipe smoking is enjoying time and the smoke. Don't get caught up in the you have to have a pipe for this and that if it's not something you can or are willing to do just smoke and enjoy. Yes tobaccos can ghost and ideally you will want different pipes for different blends etc, but the truth is until your pallet is refined and you have time with a pipe in your mouth non of it really matters. Back in the olden days gents had 2 pipes their every day workhorse, and their weekend fancy if they could afford one, and i bet you they enjoyed there pipes as much if not more then any of todays pipe snobs which i am self admittedly one of.
And of course Cobs belong in every mans rotation there is just something magical about a good ole cob pipe.
