ALL Laphroaig is wonderful. I have a couple of single cask bottles, which are 10 and 11 years old, and both bottled at 56+% ABV. Both are delicious, and I have not yet sampled a bad dram from them.
For me, age is almost irrelevant, it's all down to the taste, and single cask is always way more interesting and individual!
