I think he's quibbling about SPC's bourbon version of Plum Pudding including a stave, a trick McClelland introduced a few years back (not that it matters)
I've only tried the SR version of Plum Pudding so can't offer a comparison against the original. AlaskanPiper's answer is probably as good an answer as any... the SR is richer than the original. You can always look at tobaccoreviews. There are several reviewers there comparing the two.
That’s where I started but I have a hard time distilling all of the descriptors. Also, I see a lot of this vs. that in both directions. A lot of folks saying the regular version is the better buy, others saying they’ve never had as fine a blend as the SR version.
My two cents - I can’t make much sense (yet, I hope) of a lot of these reviews. In my opinion, the SR seems a little creamy, with a soft mouthfeel and somewhat of a nuttiness about it. That’s about all I’ve got. I don’t find raisins, plums, treacle, any of the stuff mentioned on tobaccoreviews.com.
I hope to one day get there, but right now I’m just wondering if there’s a “SR is a stronger version, flavor wise, of the regular version.” Or something like “The SR smooths out the strength of the regular version.”
Just something to put the two into perspective. I pay attention when a handful of folks on here share their opinion, simply because I have followed their advice in my short pipe career and have been subsequently rewarded by doing so - alaskanpiper is one of them. In fact, I have the SR version on his recommendation. After stoving it, I’m borderline in love with it and see myself going deep on it, just didn’t know if I could get more bang for my buck by buying the regular version in bulk, instead, is all.
