Congrats on your new Pete, I hope you enjoy it.
In regards to bent pipes, every bent pipe I own passes a pipe cleaner with ease except for one and that one just needs a little twist. Just because it is bent does not mean the maker gets a pass on not constructing it properly. All pipes should pass a cleaner except for system pipes and maybe those Oom Pauls. Every bent Savinelli, Upshall, Castello, Radice, Caminetto, Winslow,Viprati, Ser Jacobo, Spanu,Dunhill, Charatan,Willmer and of course all of my artisan pipes over the years pass a pipe cleaner. The only two pipes I bought that did not were a Nording and a full bent Mastro De Paja and I was brand new to pipes and did not realize I should never have bought them. You never have to settle for a pipe that does not pass a cleaner, always ask the seller to check it for you and never accept one that does not. Any pipe that does not pass is mis drilled and should not have been sold. It is one of the most important features you need to look at when buying a pipe.
edit. Also price is not an issue in this, I don't care how low a price the pipe is, it should still pass.
