I suppose I could have done a much better job of setting up this topic for discussion. I believe the 12yr Signature and 15 yr Single Barrel offerings from Balvenie are very similar. I have a preference, as I have tasted both of them, but I am curious what others think about them.
Same with Glenfarclas 15 and 17. I have tried both, but I am curious as to other's opinions.
As for the sherry bombs offered at or near cask strength, I prefer A'Bunadh, with Mac CS coming in second. I don't care much for 105.
