papipeguy, I wonder if the Lane RR is like the Match ERR?
As for CH vs PA...this first year of my smoking a pipe I began with some crappy ohm roll your own 'pipe' tobacco and quickly got hip to real pipe tobacco. The rush was on to taste and experience a variety and get 'up to speed' on this new found treasure trove.
My first OTC codger blend was SWR and it took me awhile to become its fan.
I tried PA next...and again...it took awhile...
The same happened with CH...but, I was realizing that, for me, these new blends required my brain and taste buds to become receptive of their individual nuances.
One of the hardest to 'get' was Half and Half. It seems to be one of the more 'cased' codgers with a very strong tin note and it was hard for me to smoke at first w/o tongue burn.
Each of these blends must have a slightly different PH level in addition to their other contrasts, which include cut, ratio, casing, topping, flavor, and appearance. That PH seems to affect the taste buds and require learning.
