@jpmcwjr I'm alive, no need for the missus to break out the champagne just yet!
Sorry it took a while to get around to testing, but I did just a few minutes ago. As a disclaimer, I am new to piping and cannot make a proper review since this is only the 3rd type of tobacco I've ever tried.
I checked the label and found that the MacBaren Original Choice #01 RYO I purchased is made of "Silk cut Virginia, Burley and Orient tobaccos with a sweet vanilla and caramel flavour." The first thing I noticed was, of course, the cut is so much finer than the usual pipe tobaccos I use. I packed it a bit looser since it has a tendency to clump together at the onset. I picked it apart a bit to make sure air flows through the pipe.
I noticed a bit more tongue-bite, but apart from that, I did not notice any drastic difference with my other blends. The pipe got hot at the same level, similar level of light-headedness after my usual bowls. It burned through the bowl nicely, I did not need to relight after the initial lighting, which was not the case with the others. The residue was a very fine ash and the pipe cleaner came out with much the same discoloration as the usual.
As pointed out by a few of you, it seems that the only difference with MacBaren's RYO is with the cut. It has a milder flavor than the Captain Black Cherry and Borkum Riff Honey and Orange in my limited arsenal. I will keep a closer watch on the RYO but I think I won't have any problem including it in my rotation.
