I have two "stinger pipes". A Kaywoodie and a Sir Hubert. And I have a couple Grabow and a cob. These are my regular smokers (I don't have a huge or high end collection, as you see).
I actually rehabbed the Kaywoodie into a decent smoker, fixing the stinger position and the carburetor.
In any case, the stinger pipes do smoke a bit different, and cleaning them is a bit more labor intensive, but not hugely so. The biggest difference, to me, is making sure you use the very thin diameter cleaners and pushing slowly with the cleaner so that it can "make the bend" in the stinger. Once a bit pokes out, you can pull it through.
It is possible that the thin tube on the stinger makes cleaning a bit easier, as it comes out very clean after two pulls, like someone noted.
To me, and just me, I wouldn't circumcise the thing. It smokes a little different, but it is just part of the personality of the pipe. Maybe it will suit a particular blend, or a smoking style, that other pipes won't, or won't as well.
