This is fairly normal. First, the draw of a pipe will make you regulate your puffer/sipper balance differently; second, for many reasons, different blends taste differently in different pipes. I would stop packing your favorite tobaccos in small pipes and enjoy them in the full size pipes. Do we really care why this is true?I smoked both of these tobaccos in my full size pipes (Luca Vanetti and Corleon) and they are absolutely awesome, I taste and smell every flavor and enjoy them. But when I pack them in to the smaller pipes and smoke them, all I taste is plain smoke. The flavor and aroma disappears.
