Had a San Lotano Oval about a month ago and I couldn't really pick out anything out of it aside from, as you mentioned, that Padronesque, Nicaraguan tobacco flavour and that heavy black pepper spice that is so common in those cigars.
Interesting that you bring this up because I had an OR 85 Padron last night and the the first third was nothing but those same flavours, however, after that it definitely became more interesting. The aroma became more intense with a pretty heavy blueberry smell, very much like older 80s. Had a bunch of leather and coffee on the palate, and a couple of these really interesting flavours popped up here and there that I can't describe, but I really hope they become more prevalent with another year or two of ageing. Also, thankfully no burn-the-shit-out-of-your-nostrils spice in the last two thirds either; certainly no Quai D'orsay, but very smooth.
